Description
The system runs both grid-tied and off-grid, and in off-grid mode it feeds loads of up to 2,500 W. While the grid is present, power to the loads passes through the unit, with a pass-through current of up to 30 A. The versions differ in AC output, while every one of them has the same 2.56 kWh battery. At 800 W it lasts roughly three hours, at the full 2,500 W about an hour. During the day the battery charges from the balcony panels, and in the evening it feeds the apartment and cuts grid purchases. The kit fits where a large battery is not needed or there is simply no room for one.
How to choose
Pick the version by panel power and by what has to run during a blackout. A fridge, router and lighting need 800 or 1,600 W, while a kettle or microwave calls for 2,000 or 2,500 W. If 2.56 kWh is not enough, the next step is the RW-F5.1-1H2 / RW-F5.3-1H3 at 5,000 W with 5.12 / 5.32 kWh units that scale up to 16 pieces.
