The SUN-3/3.6/4/5/6/6.6K-OG03LP1-EU is Deye's dedicated off-grid inverter family from 3 to 6.6 kW (including a 24 V 3 kW model), pairing 48 V lead-acid or lithium battery banks with up to 140 A of charge/discharge current and 2x PV oversizing for higher energy yield. Larger AM2 models offer dual 18 A MPP trackers to support high-power PV modules.

It delivers 200% peak output for reliable high-power start-up, 4 ms ultra-fast switching for sensitive loads and 97.6% conversion efficiency, and up to 16 units can be paralleled to build larger off-grid systems. Grid and generator inputs can recharge the battery, the IP65 housing runs below 46 dB, and Deye Cloud provides remote monitoring and configuration — with a standard 5-year warranty, extendable.
