Batteries:

We offer different batteries, from Germany, Canada and other European producers. We use sealed “gel” or absorbed glass-matt (AGM) type lead-acid batteries to avoid all battery maintenance. OPzV batteries are based on tubular plate technology and the fixing of the electrolyte as gel. The construction as sealed batteries makes OPzV batteries maintenance free.
Most off-grid solar and battery back-up systems use an open-cap deep-discharge liquid lead-acid battery.
Depending on the size of your PV-Solar system and location we choose best batteries for your application.
