DAH Solar Displays 3-Phase Hybrid Inverter & Battery At Intersolar

During Intersolar Europe 2025, DAH Solar, well-known for balcony solar systems, promoted its latest inverter and battery models. It also showcased its frameless PV modules.  

DAH Solar says it developed its new 3-phase hybrid inverter – DHN-LVEH3P8~12K-G1 – based on its know-how in building the microinverters for its balcony solar systems, which it calls ‘SolarUnits’. Among the product’s key features, the company emphasized safety – featuring DC-arc fault protection. During arc formation, an electric spark between 2 broken DC circuits might lead to fire, which activates this feature and disconnects the inverter. According to the company, thanks to its embedded artificial intelligence (AI) algorithm, this safety feature can be ‘quickly’ activated to prevent potential safety hazards. On the performance side, compatible with an AC-coupled energy storage system (ESS), the inverter can be combined with both battery units and PV arrays. Its battery port, designed to support up to 60 V battery units, can absorb or deliver up to 240 A DC. Engineered for up to 160% DC/AC photovoltaic (PV) oversizing and equipped with 2 MPPT channels, the hybrid inverter offers up to 12 kW 3-phase output power. 

The company’s booth also debuted its lithium iron phosphate (LiFePO4) single battery unit, DHN-LVWES15-G1. Compared to the above-mentioned hybrid inverter’s arc fault safety feature, this storage unit features an optional fluorine ketone gas-based fire-suppression system – a key feature, underscores the company. It can mitigate potential fire hazards due to electrical or thermal runaway events. Also, its integrated battery management system (BMS), which is an ‘intelligent’ controller, ensures safe and efficient operation for more than 6,000 charging/discharging cycles. With a battery capacity of up to 280 Ah, it can store a maximum of 14.34 kWh of energy, which can be charged or discharged at a nominal 140 A DC.  

Also on display was its ‘Full-Screen’ PV module, which eliminates the frame from both long and short sides to form 128° curved edges. It features anti-dust properties, limiting any potential localized dust deposition, especially along the edges of front side frames. According to the company, it might result in potential energy gains of between 6% and 15% compared to frame-based standard module. The company demonstrated the anti-dust properties of its frameless 460 W PV module, even at a low inclination angle, compared to standard module, by placing the former over a horizontal plane.
