Features
- PV, utility and battery can supply the load simultaneously.
- Built-in MPPT — solar panels connect directly, no external charge controller needed.
- Smart temperature-controlled fan — quiet at low load.
- High-frequency design — light and compact for its power density.
- 360° protection — over-voltage, under-voltage, overload, short circuit, over-temperature, reverse polarity and surge protection.


Typical loads
The 1200 W output is best matched to a defined, modest load. Three configurations the manufacturer documents:
Remote rural household. One or two efficient refrigerators (150–200 W each), four to six LED lights (20–40 W each), a television (80–120 W) and phone chargers — total under 800 W. Pair with a 12 V 200–300 Ah LiFePO4 battery and a matched PV array.
Small agricultural use. Irrigation controls, a small ventilation fan (60–100 W), an automatic feeder (30–50 W) and a heat lamp (50–80 W).
Market stall or small commercial point. LED strip lighting (30–50 W), a small freezer (150–200 W), a cash register (20–50 W) and small catering equipment up to 500–800 W.
Sizing notes
The PV input limit of 800 W is the binding constraint, not the output. A 1200 W inverter with only 800 W of PV will not recharge a large battery bank quickly. If the battery is 300 Ah at 12 V (3.6 kWh), and the load draws 2 kWh per day, the array needs to deliver roughly 2.5 kWh per day including losses — feasible within 800 W over 4 peak-sun hours, but not with much margin.
Battery voltage is fixed at 12 V by this model. At 1200 W output that means up to about 100 A of battery current, so battery cable size matters. Use the installation guide for cable and breaker ratings.
