Each module has one defined role in the stack. The main base controls the system; batteries add stored energy; extra inverters add independent AC output; and the optional chassis makes the assembled system mobile.

• Main baseThe control center. It provides pure-sine-wave AC output, accepts AC mains charging and provides the system’s only solar-input port.
• Extra inverterAdds an independent AC-output channel and accepts AC mains charging. It does not provide a solar input.
• Extra batteryAdds 2,400Wh (2.4kWh) of stored energy to the system.
• Off-road mobile chassisAn optional die-cast aluminum trolley with four 4-inch aluminum wheel hubs and a listed maximum load of 200kg.

No. Expansion batteries and extra inverters must be connected to the main base. The main base is the system controller, so expansion modules cannot operate independently.

The system outputs a pure sine wave designed to match grid power and support sensitive electronics plus inductive and capacitive loads. Ratings vary by regional version.

• US version3,300W rated continuous output and 6,500W listed surge peak.
• EU / UK / AU version3,600W rated continuous output and 7,200W listed surge peak.
• Instantaneous figureThe dealer-training material separately lists 13,000W for the US version and 22,000W for the EU / UK / AU version as maximum instantaneous power.

ImportantUse the rating on the exact product label and current manual when sizing a load. Surge and instantaneous ratings are not continuous-output ratings.

Yes. The system supports pass-through power, simultaneous charging and discharging, and automatic battery takeover after a mains failure. Transfer behavior depends on the module configuration.

• ≤20ms setupConnect the main base to grid power, turn on AC input and AC output, and connect protected loads to the main base AC outlets.
• 0ms setupUse a main base plus an extra inverter. Keep AC input on and AC output off at the main base; disconnect grid input from the extra inverter, turn on its AC output, and connect the protected loads to the extra inverter.
• Stacking ruleKeep one battery module between the main base and the extra inverter rather than placing the two inverter modules directly together.

The dealer-training configuration supports a 230V main base paired with a 110V extra inverter, or the reverse, so the system can provide both voltage standards at the same time through separate inverter modules.

ImportantConfirm regional compatibility, connectors and applicable electrical rules before mixing voltage standards.

Yes. The G Series USB-C output supports PD 3.0 and PPS and is designed to fast-charge many MacBook and Windows laptops.

• USB-ATwo ports, up to 18W per port.
• USB-CTwo ports sharing up to 100W of fast-charging output.

The system supports AC mains charging, solar charging and hybrid operation in which it powers loads while receiving AC and solar input.

• AC mainsUp to 1,800W for the US version and up to 2,200W for the EU / UK / AU version.
• SolarUp to 1,000W through the XT60 solar input on the main base only.
• Solar electrical limitThe training material lists up to 100V and 20A, while noting that the product label shows 11–60V for UL-certification requirements.

ImportantAlways follow the input range printed on the exact unit and the latest product manual before connecting panels.

At the maximum 1,000W solar input, the dealer-training estimate is about 3 hours for a 2.4kWh battery configuration and about 5.5 hours for a 4.8kWh configuration.

ImportantActual charging time changes with sun angle, cloud cover, temperature, shading, cable losses and battery state of charge.

The system can work with compatible panels from mainstream brands. The complete array must stay within all three listed limits: no more than 1,000W total power, 100V total voltage and 20A total current.

ImportantPanel voltage and current change when panels are wired in series or parallel. Verify the full array specification before connection.

AC charge time depends on total battery capacity and on how many inverter modules can charge simultaneously. The dealer-training estimates are shown below.

The system can reduce charging power automatically as part of its protection and power-management logic.

• Temperature protectionVery high or low ambient temperatures can trigger a lower charging rate to protect the battery.
• Charging stageBelow 10% or above 80% state of charge, the system may reduce power and use a gentler charging stage.
• Input-source limitUnstable mains voltage or a socket or cable with insufficient capacity can restrict input power.
• Output priorityWhen the system is also delivering a high-power load, it can prioritize output and dynamically reduce charging power.

The G Series supports expansion within one stack and larger linked-system configurations. Batteries increase runtime; extra inverters add independent output channels.

• One main baseConnect up to five battery packs for a maximum of 12kWh, and up to two extra inverters.
• Single-stack outputUp to 9.9kW in the US, 10.8kW in EU / UK / AU and 9kW in Japan.
• Linked capacityAcross linked systems, the training material lists up to 23 battery packs and four extra inverters for as much as 55.2kWh.
• Linked outputUp to 16.5kW in the US, 18kW in EU / UK / AU and 15kW in Japan.
• Maximum-output configurationThe deck specifies four extra inverters with at least 10 separately connected battery packs to reach the listed linked-system maximum output.
• InstallationUse the dedicated connecting cables for linked systems and alternate inverter and battery modules rather than grouping all inverters together.

It is a single-phase system and does not support 380V three-phase input or output. It can be used as a household backup power source when connected through an appropriate, isolated backup configuration.

The dealer-training material describes a simple plug-in method for individual appliances and a professionally installed transfer-switch method for selected circuits or whole-home backup.

• Individual appliancesPlug the main base AC input into a wall socket, then plug the appliances that need backup power into the system’s AC outlets. Automatic transfer activates after a mains failure.
• Home circuitsA certified electrician installs an Automatic Transfer Switch (ATS) in the distribution panel so selected circuits can be physically isolated and transferred to storage power.
• Included switchThe training deck states that a basic transfer switch is supplied, but that it does not provide intelligent power distribution or energy monitoring.
• US installationThe deck advises electricians to select a recognized NEC-compliant transfer switch, such as a suitable Reliance model, where required by local rules.

ImportantDistribution-panel work must be designed, installed and inspected by a qualified electrician under current local electrical codes.

The power station must remain electrically isolated from the public grid and must never be connected in a way that can backfeed utility lines.

• No direct grid-tieNever connect the output directly to the grid. Use physical isolation through an approved transfer switch.
• Respect channel limitsDo not exceed the rated output of an individual inverter channel.
• Use qualified materialsThe training material specifies wiring and sockets rated at 16A or higher.
• Professional installationAny distribution-panel modification must be performed and inspected by a certified electrician.

No. This portable storage system is not a grid-tied bidirectional inverter and does not provide the anti-islanding protection required for grid export. It supports one-way use: charge from an approved source, then power appliances through its own outputs or an isolated backup arrangement.

ImportantAttempting to backfeed the grid is unsafe, can damage equipment and can endanger utility workers.

The G Series uses a 48V lithium iron phosphate (LiFePO4) battery architecture with an intelligent battery-management system.

• Cell formatDFD 65120 cylindrical 50Ah cells in a 15-series configuration.
• Cycle lifeAt least 80% remaining capacity after 4,000 full charge-discharge cycles under the stated standard test conditions.
• Service expectationThe training material describes approximately 10 years of stable operation in regular household-backup use; actual life depends on conditions and usage.
• BMS protectionCell balancing plus protection against overcharge, over-discharge, over-current, short circuit and over-temperature.

The listed charging range is 0°C to 45°C, and the listed discharging range is −20°C to 45°C. Below 0°C, low-temperature protection can limit or stop charging. Cooling fans operate automatically when additional heat dissipation is required.

No. The product is not rated as waterproof or dustproof and should not be used directly in rain, sand-heavy conditions or humid environments.

The fans use temperature-controlled speed logic. The training material states that they turn on at an internal temperature of 48°C or above and shut down at 43°C or below. Heavy loads, high-power charging and high ambient temperatures can also cause fan operation.

• Main baseFive cooling fans.
• Extra inverterFour cooling fans per module.
• Extra batteryOne cooling fan per module.
• Noise behaviorThe fans stay quiet under light loads and adjust speed under heavier loads; the deck compares operating noise with casual conversation.

Yes. The EnergyKeeper app is listed for iOS and Android and connects by Bluetooth or Wi-Fi. The dealer-training material lists an approximate Bluetooth range of 45 meters under suitable conditions.

• Live monitoringBattery level, input and output power, remaining charge or discharge time, temperature and fault codes.
• Remote controlTurn AC and USB output on or off remotely.
• SettingsConfigure energy-saving mode, target charge level and other supported parameters.
• Multi-device viewManage multiple main bases and stacked systems from one app.
• Alerts and historyReceive low-battery, temperature, overload and fault notifications, and review historical energy-use records.
• UpdatesInstall supported firmware updates over the air.
• On-device screenShows battery percentage, real-time input and output power, estimated time remaining, fault and temperature warnings, AC and USB status, connected-inverter count and AC or solar charging mode.

The system includes short-circuit, overload, over-voltage, under-voltage, over-temperature and reverse-connection protection. A fault can trigger screen warnings and an audible buzzer.

• Step 1Remove the external cause first—for example, disconnect an overloaded appliance and inspect the wiring.
• Step 2Press the relevant AC or USB on/off control to attempt recovery.
• Step 3After a severe overload, use the manual overload-protection reset control on the chassis as directed by the product manual.

Power down the complete system and disconnect every power source before connecting, disconnecting, stacking or removing the main base, an extra inverter or an expansion battery. Never plug, unplug or assemble modules while energized.

ImportantLive assembly can cause short-circuit damage, equipment failure or personal injury.

Rated capacity is measured under controlled conditions. Real use includes conversion losses, startup surges, fluctuating loads, temperature effects and normal battery aging.

• Inverter lossConverting battery DC power to AC typically uses about 10–15% of the stored energy, leaving roughly 85–90% available to AC loads.
• Motor startupRefrigerators, air conditioners, drills and other motor loads can briefly draw two to three times their rated running power.
• Changing duty cycleTools and appliances draw different power while starting, idling and working, and repeated cycling adds consumption.
• Temperature and ageCold conditions can reduce discharge efficiency, while usable capacity gradually declines over long-term use.

The appliance’s steady running wattage may fit while its startup demand does not. Inductive loads and several devices starting together can exceed the inverter channel’s short-duration limit and trigger protection.

• Motor surgeRefrigerators, air conditioners, pumps and power drills can draw two to three times their rated watts at startup.
• Reactive demandInductive loads can reduce the inverter’s effective available power even when the nameplate wattage appears acceptable.
• Simultaneous startupStarting several appliances together combines their surge demands.
• Voltage dropA large instantaneous current can cause a brief voltage drop and trigger low-voltage protection.
