Questions, Answered
What panels work with this inverter?
Any panel rated 280W–550W with working voltage (Vmp) in the 25–55V DC window. Each MPPT input takes one panel and different wattages can be mixed.
How many inverters can I connect together?
Up to 4 units per branch circuit, letting you scale a balcony or rooftop system from 800W up to 3.2kW.
Do I need a battery?
No — this is a grid-tie inverter: DC is converted straight into 230V AC and fed into your home circuit. Batteries only apply to off-grid hybrid systems.
How do I set up monitoring?
Scan the QR code on the unit in the free Solarman app, connect over WiFi, and view live output, generation totals and error codes remotely.
Is it certified for EU grid connection?
Yes — VDE4105, VFR2019 and NEN/PN-EN 50549-1:2019 certified.
