Solis RHI-3P4K-HVES 4 kW Three-Phase Hybrid Energy Storage Inverter

The Solis RHI-3P4K-HVES is a three-phase hybrid energy storage inverter with a rated output power of 4 kW, designed for both on-grid and off-grid operation. It features a transformerless topology with a maximum efficiency of 98.4%, two MPPT trackers with two DC inputs, and supports high-voltage lithium-ion battery systems (160–600 V).

The inverter offers three operating modes: self-consumption, time-of-use energy shifting, and off-grid backup with up to 4 kW of continuous power and 12 kVA of peak power (for 60 seconds). Automatic power supply switching occurs within 40 ms. It includes intelligent 24-hour energy management, real-time system monitoring, and support for three-phase imbalance compensation.

It features IP65 ingress protection, natural convection cooling, and a fanless design for silent operation. Dimensions: 535 × 455 × 181 mm; weight: 25.1 kg. It communicates via RS485, with optional Wi-Fi and GPRS modules. Compatible with BYD HVS and HVM high-voltage battery systems.
