Sofar PowerAll ESI-8K-T1 Hybrid Inverter 8 kW Three-phase High Voltage
The Sofar PowerAll ESI-8K-T1 is a three-phase hybrid inverter rated 8 kW for PV systems with high-voltage storage. It works with 350-435 V battery stacks over CAN and handles up to 16000 Wp of PV across 3 independent MPP trackers.
Charge and discharge power reach 8 kW with discharge current up to 24 A, so the battery follows household loads even at peaks. In backup mode the output delivers 8,8 kVA, and twice the rated power for ten seconds, with about 10 ms transfer time and support for 100% phase imbalance: a large single-phase load is not a problem.
Peak efficiency is 98.2%, European efficiency 97.5% and MPPT efficiency up to 99.9%. The IP66 enclosure allows outdoor wall mounting from -30 to +60 °C. RS485 and CAN come as standard, with Wi-Fi, 4G or LAN optional, plus LCD display and monitoring app.
