260A Bidirectional Battery Current on the 12kW Model
The 12kW three-phase low-voltage model reaches 260A for both hybrid charging and discharge, reducing battery-side bottlenecks in a high-power 48V system. The HESP48120SH3 12kW model raises battery-side capability to a maximum 260A for hybrid charging and discharging.
18kW PV Input on the 12kW Three-Phase Model
The 12kW model can accept a larger solar array than its AC rating, leaving more PV energy available for daytime demand and battery charging. The 12kW HESP48120SH3 supports up to 18kW of PV input, arranged as 9kW + 9kW across its solar inputs.
Longer PV Strings with an 800V Input Window
Two MPPTs operate over 200–650V with an 800V PV ceiling, allowing longer strings on the low-voltage three-phase system. Two MPPT channels operate across 200–650Vdc, while maximum PV open-circuit voltage reaches 800V.
Native 230/400Vac Output for Three-Phase Loads
Native 230/400Vac three-phase output lets the HESP 8–12kW EU supply existing three-phase pumps, HVAC equipment and light-commercial loads directly from its AC side. The series delivers pure sine-wave three-phase output while retaining a 48V battery platform, so three-phase load voltage does not require a high-voltage battery architecture.
2x Peak Reserve for Three-Phase Starting Loads
The three-phase HESP 8–12kW provides up to 2× peak output for short three-phase load surges. Rated outputs of 8kW, 10kW and 12kW correspond to peak values of 16kVA, 20kVA and 24kVA, providing short-duration capacity for three-phase startup surges above steady-state load demand.
Fast Backup Transfer with a Separate Generator Input
The separate generator input adds a second backup source, while the 10ms transfer reduces the interruption when utility power is lost. A dedicated generator port provides an additional battery-charging and backup source when grid quality or solar availability is insufficient.
