Description

Full compatibility with modern 500W+ residential solar modules.

SAJ HS2-5K-T2-X is a 5 kW three-phase residential hybrid inverter with dual 16 A MPPT channels and a 30 A high-throughput battery port, engineered to harvest modern 500W+ solar modules and provide balanced 400 V emergency backup.

SAJ HS2-5K-T2-X (5 kW three-phase hybrid inverter)

16 A High-Current Dual MPPTs, 100% compatible with modern 500W+ high-power residential panels (Isc 19.2 A) with zero DC current clipping.
30 A High-Rate Battery Interface
Delivers 20% faster charging than standard 25 A residential inverters, maximizing capture during short sunny windows.
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase household circuits without drawing expensive grid electricity.
Sub-10 ms Seamless UPS Backup
Built-in automated transfer switch powers critical home electronics and heating controls continuously during outages.

More product details

Modern residential solar panels operate at 13–15 A, causing older 12.5 A inverters to clip peak midday power. The HS2-5K-T2-X provides 16 A continuous input per MPPT (Isc 19.2 A) to capture 100% of solar generation.

Dual independent MPPT channels track separate roof aspects down to 180 V starting threshold.
Wide MPPT operating voltage window (180–900 V) optimizes harvest across extreme temperature swings.
97.6% European efficiency minimizes internal thermal loss under continuous full-power export.

Faster battery charging with dynamic single-phase load compensation.

Featuring a 30 A high-voltage battery port and 100% phase-unbalanced capability, the inverter charges storage rapidly while eliminating grid import penalties on asymmetric domestic loads. 30 A charge/discharge throughput tops off 5–15 kWh battery stacks faster during brief midday solar peaks. Dynamically shifts up to 100% of capacity onto a single heavily loaded phase to prevent utility grid purchases. IP65 die-cast enclosure certified for clean indoor or sheltered outdoor installations (-35 to +60 °C).

Storage that is not scaled to the output.

The battery port belongs to the platform, not to this size: 180 to 600 V at 30 A charge and discharge, up to five BU2-5.0-HV1 or HV5 modules on a quick connector, 5 kWh to 25 kWh. Modest peak demand and a long evening is a normal combination, and this unit serves it.

Outdoors or in the garage, at 32 kg.

IP65 on a 450 x 626 x 365 mm wall unit, rated -10 to +50 °C with derating above 45 °C, running under 35 dBA. One enclosure on one bracket, with no separate battery cabinet to find room for.

Plug-in on the AC side, MC4 on the roof side.

AC lands on a plug-in connector on 3L+N+PE and the strings land on MC4 / H4. Peak efficiency is 98.0 % and European efficiency 97.6 %, which is the figure that describes a German year rather than a test point.

Project scenario

Small European Single-Family Homes (5–7.5 kWp PV) Using 500W+ Panels

Homes installing 12–16 modern high-current panels across 1 or 2 roof orientations under three-phase grid connection rules.

16 A MPPT inputs prevent current clipping on modern panels, while 5 kW three-phase output fulfills grid phase-balance mandates.

BoundaryIf the household operates an air-to-water heat pump (> 3 kW thermal) or an electric vehicle, step up to the HS2-6K-T2-X (6 kW) or HS2-8K-T2-X (8 kW) for greater electrical headroom. ---

Product questions

What is the benefit of a 16 A MPPT input over a standard 12.5 A input on a 5 kW inverter?

Eliminates midday power clipping on modern 450W–550W+ solar panels. Modern residential solar panels (182 mm cell format) have operating currents ($I_{\text{mp}}$) around 13.0 A to 14.5 A. On a 12.5 A inverter, any current above 12.5 A is discarded as heat. The HS2-5K-T2-X’s 16 A rating (19.2 A Isc) extracts full rated power from modern panels during bright summer hours.

What battery systems are natively compatible with this model?

SAJ B2-HV1 / B2-HV5 high-voltage battery towers (180–600 V). The inverter connects directly via CAN communication to SAJ B2-HV1 and B2-HV5 high-voltage battery stacks (from 5.0 kWh / 102.4 V up to 25.0 kWh / 512 V), utilizing its 30 A charging capability for rapid energy storage.

Item number: DLK-SAJ-BU250HV1

The HS2 datasheet's scalability row reads 'BU2-5.0-HV1/5, up to 5 battery modules', and that row is identical on the 5 kW column: dropping to the bottom of the ladder does not reduce the battery bank you can put behind it.
