At the Intersolar Europe 2025 event in Munich, Germany, several PV inverter and storage solution providers showcased their diverse product portfolios, all targeting Europe’s residential market.
Solplanet, a Chinese provider of PV inverters, EV chargers, and smart monitoring solutions, was one among these, presenting its full range of offerings. Visiting the company’s booth, the TaiyangNews team spoke with Bo Lønborg Müller, Director of EMS & Apps, who introduced the ASW H-T2/T3 series: a 3-phase hybrid inverter designed for European residential consumers, supporting connected loads of up to 12 kW.
Hybrid Inverter
Performance
Müller explains that the T2 series (ASW H-T2), operating at a 1.1 kV system voltage level, is equipped with 2 MPPT channels, while the T3 variant (ASW H-T3) features 3 MPPT channels.
The T2 model supports a single PV string with a maximum input current of 20 A and can connect to a PV array with a capacity of up to 18 kW. In comparison, the T3 variant accommodates a single string with a maximum input current of 16 A, also supporting up to 18 kW of PV capacity.
Both models include an integrated battery port, which, when paired with the Ai-HB G2 series high-voltage battery bank, can operate in either hybrid or PV + AC-coupled mode, Müller noted. According to their datasheets, the T2 and T3 inverters, when integrated with the LiFePO₄-based battery bank, can charge or discharge up to 12 kW of power, with a maximum current of 30 A.
The Ai-HB G2 battery bank includes 3 battery units, each with 2.56 kWh capacity, and uses 50 Ah LiFePO₄ cells. For users requiring greater energy storage, the system supports up to 8 battery units, scaling total storage capacity to 20.48 kWh. When paired with this full stack, the hybrid inverter can charge or discharge up to 10.24 kW, with a continuous charging current of 25 A and a discharging current of 30 A.
Designed for up to 150% DC/AC oversizing, both the T2 and T3 inverters, when coupled with the battery bank, can deliver a 3-phase output current of up to 19.2 A. In the event of a grid failure or load shedding, the system switches to EPS mode in under 10 milliseconds and can supply up to 12 kW of flicker-free 3-phase backup power. Notably, to support high-capacity critical loads, the EPS mode can also deliver up to 24 kW of peak output power for 10 seconds, Müller added.
Safety
With an IP66-rated enclosure, the T2 and T3 series hybrid inverters offer multiple safety features and protections on both the DC and AC sides. To safeguard against surge voltages, typically caused by lightning strikes, each unit is equipped with an integrated Type-II DC surge protection device (SPD).
To mitigate potential equipment damage or fire hazards stemming from PV arrays with low insulation resistance (IR), the system periodically checks the IR value of the connected array, typically during inverter startup. For added installation safety and ease of use, it features reverse polarity protection for both the PV string and battery port.
The inverter also includes anti-islanding protection, allowing utility personnel to safely perform maintenance at the inverter’s output terminal during a grid shutdown. Additionally, the system is engineered to withstand AC short-circuit current and leakage current on the AC side.
Other Features
Aligned with Europe’s latest time-of-day (TOD) and dynamic electricity tariff regulations, the intelligent work modes of both inverter variants can manage the battery’s depth of discharge (DOD) and optimize energy usage based on regional tariff structures.
In terms of compatibility, the ASW H-T2/T3 series can integrate with immersion heaters, heat pumps, and Solplanet’s Sol Apollo EV charger, ensuring a flexible and comprehensive energy management solution.
