Description

The Solplanet Ai-HB Pro 125A is a five-module tower, 12.8 kWh (usable 12.16 kWh), 256 V nominal voltage, 171 kg, 860 mm. A configuration for a house with a heat pump and an 8–10 kW three-phase Solplanet hybrid plant: the capacity covers a winter evening with heating, and there is still margin below the 15 kWh limit of the planned APVA call – the compensation is calculated for the full 12.8 kWh.

Power for a heat pump

256 V at the inverter's 30 A battery current (ASW 08–12kH-T3) gives about 7.7 kW of battery power; for the ASW08kH-T3 that is almost its full 8 kW battery power. The heat pump, the oven and household appliances run together from the storage in the evening. The tower's own limit is 50 A (12.8 kW, 1C).

125A or 150A

The sixth module (150A, 15.36 kWh) makes sense when the plant is 10 kW or more and a surplus still remains in autumn and winter; with an 8 kW plant the five-module tower is filled more reliably. The difference between them is one module: 2.56 kWh, 31 kg and 130 mm of height, which you can add later on the same BCU (up to 8 modules).

Installation and location

A 540 × 390 mm base on solid concrete or masonry, the BCU wall-fixed with two L-brackets. IP65 – a garage, a boiler room, outdoors under a roof, not in direct sunlight; discharge from −28 °C, charge from +2 °C. The 200–292 V voltage window fits within the 120–600 V range of the ASW kH-T3.

Inverter compatibility

Officially compatible with Solplanet ASW05–12kH-T2, ASW08–12kH-T3, ASW05–12kH-T2-DG, ASW08–15kH-T3-DG and ASW015–030K-TH; CAN communication over RJ45, Ai-HB G2 Series selected in the app. Not listed for single-phase Solplanet hybrids. We check your inverter model against its label before the order.

Safety and warranty

LiFePO4, an aerosol extinguisher in every module, a circuit breaker and BMS protections, 8,000 cycles, certificates IEC 62619 and VDE 2510-50. AISWEI warranty – 10 years or up to 36.48 MWh of delivered energy, whichever comes first. Under the terms of the planned 2026 APVA call the compensation is calculated per capacity (170 €/kWh, up to 15 kWh).
