About this product

Overview

The Sosen HL15K-P3EU is a three-phase hybrid inverter rated 15kW in and 15kW out at 380/400 Vac (3W+N+PE, 50/60Hz). It works with either lithium or lead-acid batteries at a nominal 51.2V (40~60V range) and can charge or discharge at up to 315A. Two MPPT trackers with 2+2 strings accept up to 30kW of PV, with an MPPT window of 150~950 Vdc and a 1000 Vdc maximum DC voltage.

It is built for homes, shops and small businesses that want solar with battery backup on a three-phase supply, and for retrofit sites where an existing grid-tied system needs storage added (AC coupling is supported, and up to 8 units can run in parallel). For Uganda, where grid outages are common and three-phase loads such as pumps, freezers and workshop machinery are widely used, the off-grid overload of 200% for 10s, 150% three-phase unbalanced output and IP66 enclosure make it practical for dusty, hot and sometimes wet sites; 0-95% non-condensing humidity and derating above +45°C. Monitoring is via LCD and app over RS485/WiFi/CAN, with optional Bluetooth, LAN or meter.

Frequently Asked Questions
What battery voltage does the Sosen HL15K-P3EU need?
It uses a low-voltage battery with a nominal voltage of 51.2V and a battery voltage range of 40~60V. Both lithium and lead-acid batteries are supported.
How much solar PV can it take?
Maximum PV array power is 30kW, with a maximum DC voltage of 1000 Vdc, an MPPT operating range of 150~950 Vdc and a start-up voltage of 180 Vdc. There are 2 MPPT trackers with 2+2 strings, max input current 4*20 Adc and Isc PV absolute maximum 4*30 Adc.
Is it single phase or three phase?
Three phase: 380 / 400 V a.c., 3W+N+PE, 50/60 Hz output, 15kW / 15kVA rated, with a maximum continuous current of 43/22 Aac.
Can I parallel several units?
Yes. The parallel function is supported for up to 8 units, and AC coupling is supported for retrofit onto an existing system.
How much surge can it handle off-grid?
Overload capacity off-grid is 200% for 10s, with 2x load surge for 10s and 150% three-phase unbalanced output.
Can it be installed outdoors in hot or dusty conditions?
The enclosure is IP66 and operating ambient temperature is -25°C to +60°C, linearly derating to 60% when exceeding +45°C to +60°C, with 0-95% non-condensing humidity, permissible altitude 4000 m (>2000 m derating) and noise below 40 dB.
How is the inverter monitored?
It has an LCD + App display, and interfaces for RS485 / WiFi / CAN / DRM, with optional Bluetooth, LAN or meter.
