2kWh Off Grid Energy Storage System with 550W Solar and 1000W AC Charging

This 2kWh off grid energy storage system combines a 2000Wh LiFePO4 battery, 1000W pure sine wave inverter, 550W solar input and 1000W AC charging. It is designed for selected loads at cabins, remote offices, communication stations and temporary work locations.

Map the Complete Off-Grid Operating Day

A larger off-grid station should be selected from a 24-hour load schedule. Record the normal power, operating period and importance of every connected device.

The 2000Wh capacity represents nominal stored energy. Available AC energy will be lower after inverter efficiency, internal demand, environmental conditions and backup reserve are included.

Plan the 550W Solar Recovery Window

The solar input accepts 12–60V and up to 550W. The panel arrangement must remain within the voltage range during normal operation and maximum open-circuit conditions.

Solar sizing should account for the energy consumed by daytime loads as well as the energy needed to recharge the battery. A system using nearly 2kWh per day requires enough panel production to replace that energy within the available sunlight period.

Shade, panel temperature, orientation and poor weather can reduce daily charging. An off-grid design should not rely on maximum panel power throughout the day.

Use 1000W AC Charging During Low-Solar Periods

The AC input accepts 90–280V and supports up to 1000W charging. This provides a faster recovery path from compatible utility or generator power.

When a generator is used, its continuous capacity should cover the station charging demand together with any other connected generator loads.

The supplied specification lists a 60Hz platform. Generator frequency and load frequency compatibility must be confirmed before commissioning.

Control Power Demand within the 1000W Output

The inverter supplies a rated 1000W pure sine wave output at 220–240V. Combined continuous loads must remain within this limit.

No separate surge-power value is listed in the supplied table. Pumps, compressors, refrigerators and motor-driven tools should therefore be reviewed before being included in the load plan.

USB and PD 20W Type-C outputs provide direct charging for compatible electronics, although their consumption still reduces the battery reserve.

System Boundaries and Site Placement

The station integrates the battery, inverter and charging functions. Solar panels, generator equipment, extension wiring and site-specific protection are separate project items.

The unit weighs 18.5kg net and can be relocated when needed. It should remain on a stable surface in a dry, covered and ventilated location.

2kWh Off-Grid System FAQ

Is this a complete solar power system?

It integrates battery, inverter and charging functions, but solar panels and site wiring are selected separately.

Can it supply every load in a cabin?

Suitability depends on simultaneous power, daily energy use and whether high-consumption loads are restricted.

Can a generator recharge the station at 1000W?

The generator must provide compatible voltage, frequency and sufficient stable power after other loads are considered.

Can the system operate a pump or compressor?

The equipment’s startup demand must be confirmed because no separate surge-output rating is stated.

What information is needed for project sizing?

Provide the 24-hour load schedule, peak power, solar conditions, generator data and required emergency reserve.
