Description

High-current solar absorption across multi-pitch residential roofs.

SAJ HS2-8K-T2-X is an 8 kW three-phase residential hybrid inverter delivering 8,800 VA maximum apparent power and 12 kWp solar intake across dual 16 A MPPT channels, engineered to sustain domestic EV charging and heat pump baselines.

12,000 Wp Solar PV Input (150% Oversizing)
Dual 16 A MPPT channels capture maximum energy across large 24–30 panel residential arrays.
8,800 VA Apparent Three-Phase Power
Provides strong continuous power to run domestic appliances, heat pumps, and backup sub-panels.
30 A High-Rate Battery Interface
Fast DC charging across 180–600 V storage banks (such as SAJ B2-HV1 / B2-HV5).
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase circuits to eliminate peak grid demand charges.

More product details

Modern residential solar panels operate at 13–15 A, causing older 12.5 A inverters to clip peak midday power. The HS2-8K-T2-X provides 16 A continuous input per MPPT (Isc 19.2 A) to capture 100% of solar generation across 12 kWp arrays.

Dual independent MPPT channels optimize 24–30 panel arrays down to 180 V starting threshold.
Wide MPPT operating voltage window (180–900 V) optimizes harvest across extreme temperature swings.
98.0% peak conversion efficiency (97.6% European efficiency) minimizes internal thermal heat generation.

Dynamic single-phase load compensation with 8.8 kVA emergency backup.

Managing three-phase domestic loads with uneven single-phase appliances requires individual line regulation. The HS2-8K-T2-X shifts power dynamically to cover heavy single-phase spikes directly from solar and battery. Delivers up to 100% of capacity onto a single heavily loaded phase to eliminate peak demand grid charges. 30 A high-voltage battery port pushes up to 8 kW continuous DC power into storage (180–600 V). Sub-10 ms automatic transfer switch powers domestic emergency sub-panels during utility outages.

Five BU2 modules at 30 A.

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 added a module at a time. SAJ lists this pairing directly in its own documents.

The same 32 kg enclosure as the rest of the range.

450 x 626 x 365 mm at IP65, rated -10 to +50 °C with derating above 45 °C, under 35 dBA. Nothing about the wall, the bracket or the clearances changes between 5 and 10 kW, so a late change of output class does not move the mounting.

11.6 A per phase, 12000 Wp on the roof side.

Rated current is 11.6 A and maximum 13.3 A at 230 V, on 8800 VA of apparent power. The array ceiling is 12000 Wp across two 16 A trackers, half again the AC rating.

Technical data

The high-throughput residential energy hub engineered for multi-person electrified households.

12.0 kWp DC input with 8.8 kVA apparent power for all-electric domestic setups.

Sized for high-consumption family homes, the HS2-8K-T2-X effortlessly manages the high power throughput demanded by domestic EV wallboxes and modern heat pumps. It provides 8,800 VA maximum apparent power, routing surplus daytime generation directly into high-voltage storage while delivering clean three-phase conversion with 100% phase-unbalanced compensation.

Project scenario

Standard European 10–12 kWp Residential Rooftops (24–30 Panels)

The most common residential array size in Europe, typically installed across South/West or East/West pitches on detached family homes.

12 kWp DC intake across two 16 A MPPTs captures peak solar generation without clipping, delivering 8.8 kVA apparent power to run domestic appliances and charge storage simultaneously.

Product questions

What size AC circuit breaker and cable cross-section are required for the HS2-8K-T2-X?

16 A or 20 A 3-pole circuit breaker; 5 × 2.5 mm² to 5 × 4 mm² copper cable. The inverter has a maximum continuous AC output current of 13.3 A per phase (at 400 V three-phase). A 3-pole 16 A or 20 A miniature circuit breaker (MCB) paired with 5 × 2.5 mm² copper conductors (or 4 mm² for longer runs) is standard for European installations.

How does the 100% phase-unbalanced output benefit a home with single-phase appliances?

Prevents drawing expensive peak grid power on overloaded phases. If your home draws 3 kW on Phase L1 (e.g. washing machine + kettle) and only 500 W each on L2 and L3, standard inverters export power symmetrically (~1.3 kW per line), forcing you to buy 1.7 kW from the grid on L1. The HS2-8K-T2-X dynamically shifts internal inverter power to supply 3 kW directly on L1, keeping net grid electricity import at zero.
