Compact. Robust. Plug & Play.

A new generation of solar charging

Our SOLmini series are PWM-controlled battery charger controllers – directly integrated into the PV panel’s junction box.
Available in various current classes (0–9A) and battery voltage ranges (9V–48V), over 20 models are already in production – with custom designs available on request.

​

🔑Why SOLmini?

• ✅ Plug & Play scalability – connect multiple SOLminis in parallel for more power.

• ✅ All-in-one design – no extra cabling or separate chargers needed.

• ✅ Maximum protection – IP65+ against dust, humidity, and extreme conditions.

• ✅ Field-proven worldwide – from Antarctica to the rainforest, powering weather stations, garage doors, camping gear, and more.

• ✅ German-engineered reliability – robust electronics, optimized for high temperatures.

How it works

Conventional PV systems require separate chargers with extra cabling – often fragile, less efficient, and less protected.
SOLmini changes the game: the charger is built directly into the panel’s junction box. That means fewer parts, higher durability, and simplified installation.

​

🛠 And the best part is:

YOU decide how much energy you need and can easily expand your power supply yourself: plug & play. Endlessly. 

Get one or two more SOlminis and you've got your solution.
Just as you need it.
