PV-modul integrated battery charge controller SOLmini (IP65)

Our SOLmini series of PWM controlled battery charger controller are integrated into the PV-panel's junction box. SOLmini's are available for various current (0-9A) classes and battery voltage  ranges (9V-48V). Over 20 different SOLmini models are currently manufactured and we provide some of them as custom models.

The great advantage of the SOLmini application: You can connect SOLmini`s endlessly in parallel simply by plug-and-play to get more power of your devices.

Please find more information how to use robust SOLmini at your convenience in our SOLmini flyer in the download area at

The SOLminis are typically used in remote areas - our customers use them even at the Antarctica or at the rain forest for weather monitoring stations as well as for "simple" garage door openers and camping.

Conventional PV-solar systems charging batteries comprise typically a PV-panel and a separate IP20 protected battery charger with additional cabling / assembly effort and consequently lower robustness against dust and humidity.

The EMPO-NI SOLmini avoids additional cabling and provides typically min. IP65 protection degree - same like the box it is integrated into. Simple. Robust.

Our new approach is to use the inside space of suitable junction boxes with a high ingress protection degree as housing for our high temperature enduring electronics and to implement in this way a dedicated specially matched solar battery charger for the PV-panel.
