About this product
This SUMRY off-grid inverter comes in 4KW and 6KW versions, both at 120V and both designed for a 24V battery bank, with an integrated 140A MPPT controller for up to 5600W of solar PV and an LCD for system status. The dual rating is useful because you can size the inverter to your real peak load: 4KW for a cabin or small backup, 6KW if you also want to run well pumps, fridges or tools at the same time. Pure sine wave output keeps motors and sensitive electronics happy. Before ordering, check your battery voltage (24V), confirm the PV array stays within 5600W, and add up the starting surge of any motor-driven appliances.
