APsystems ELS-5K 5 kW AC-coupled battery inverter, single-phase, 48 V

The APsystems ELS-5K is a first-generation smart Power Conversion System designed for residential AC-coupled battery storage. It connects to a 48V low-voltage battery system and delivers intelligent energy management with automatic modes for backup, self-consumption, and time-of-use optimization.

Rated at 5000VA continuous output with peak backup power up to 7500VA, the ELS-5K achieves maximum efficiency of 96.5%. It features integrated monitoring, WIFI connectivity, and multiple communication ports (Ethernet, Wireless, RS485, CAN). The unit operates naturally cooled in ambient temperatures from −25°C to +65°C with IP65 protection.

Compatible with lithium-ion batteries (50–800Ah capacity), the inverter supports automatic BMS adaptation with maximum continuous charge/discharge currents of 100A. It complies with major European grid standards including VDE-AR-N 4105 and IEC/EN 62477-1.
