What this unit is approved to run with.
Every pairing below traces to a manufacturer compatibility list, by document version and date. A pairing only one maker lists is marked; we quote it, an engineer confirms it.
Pick the rating
HS3 family. Same engineering, different size.
Every figure comes straight from the manufacturer's official datasheet.
Configuration 2
All five models (5, 6, 8, 10 and 12 kW) take 1 to 8 plug-in BU3-5.0-TV2-PRO modules, giving 5 to 40 kWh per tower.
- Arithmetic: 8 x 5.0 kWh = 40 kWh at full expansion.
- No field cabling: the modules stack under the inverter without battery cabling to run at the installation.
- Chemistry and window: high-voltage LiFePO4 with a 380-500 V battery voltage range.
- Not the BU2: the HS3 does not take the BU2 module; SAJ's Configuration Instructions pair the BU2 with the HS2 only.
Yes. SAJ offers the CU2-11K-T-I EV charger as an optional module of the same tower, ordered separately.
- Charger rating: 11 kW at 400 V, 16 A, per the SAJ datasheet.
- Transfer switch: the SAJ ATS1-T63-A (three-phase, 63 A) lists the HS3-5/6/8/10/12K-T2 models by name in its compatibility row.
- Metering: SAJ's accessories catalogue specifies the Chint DTSU666 three-phase meter, which matches the three-phase HS3 connection.
Operation & warranty 1
SAJ rates backup output at the inverter's full on-grid power: 5,000 W backup on the 5 kW model and 10,000 W on the 10 kW model.
- Peak reserve: 7,500 VA (5 kW model) and 15,000 VA (10 kW model) apparent power for 60 s.
- Switchover: SAJ lists a 20 ms UPS transfer time on the 6 kW datasheet.
- Output quality: output voltage distortion (THDv) below 3% on linear loads.
- Whole-load backup: for switching the full installation between grid and backup, the SAJ ATS1-T63-A transfer switch lists the HS3 models by name.
Installation & wiring 1
Yes. The tower is rated IP65 and operates from -30 to +50 C with integrated heating, per SAJ's datasheet.
- Cooling and noise: natural convection, below 35 dBA, usable up to 3,000 m altitude.
- Handling: the inverter head weighs 34 kg (450 x 695 x 170 mm) and each battery module 53 kg (420 x 695 x 170 mm); the whole tower keeps a 170 mm depth.
- Protection: Type II surge protection on both DC and AC sides, with integrated AFCI, anti-islanding, overload and AC short-circuit protection.
Availability & compliance 1
SAJ's HS3 documentation lists VDE-AR-N 4105, VDE 0126-1-1, EN 50549, G98, G99, G100 and EN 62109-1/2.
- Also listed: CE, CEI 0-21 and IEC 62619 appear on the 6 kW model's specification set.
- Per-model check: certificate sets are printed per model and datasheet revision, so we confirm the exact certificate documents for your rating with the quote.
- Documents: the SAJ HS3 datasheets are linked on this page for the grid operator submission.
