Refurbished REFUsol Inverters – Tested, Overhauled, Ready for Use

Has your REFUsol inverter failed, and is a replacement unit of the same model nearly impossible to find? We’re here to help.

We maintain a pool of 90 units consisting of used REFUsol inverters of types 802 and 867, whose electronics we thoroughly overhaul. Each unit is repaired and tested by our experts and is only offered for sale once it is operating reliably. This way, you get a suitable replacement for your existing PV system without having to modify the inverter, wiring, or system design. Please note, however, that this offer includes only the unit itself, without the accessory kit. The wall mount can be requested separately if needed.

To be honest: These are used units. The housing and surfaces may have scratches, dents, or other signs of wear. These cosmetic imperfections do not affect functionality. What matters is what’s inside, and that’s where we focus our attention.

Sustainable Instead of Buying New

Every refurbished unit extends the service life of a functioning system and prevents electronic waste. In this way, we work with you to contribute to the energy transition.

Radeberg isn’t just known for good beer—it’s also home to the perfect inverter for your existing system.

We have various models and power ratings in stock. Just let us know which device you need or what’s currently installed in your system. We’ll be happy to tell you what we have available for you. It’s best to inquire right away while supplies last. We offer a 6-month warranty starting from the date of commissioning. If the unit has been in storage for over 1 year, we recommend a gentle ramp-up before commissioning (to protect the DC link capacitors), which we’ll perform upon request when you return the unit to us.
