The Steca PR 3030 was designed for photovoltaic systems to charge 12V and 24V batteries. In contrary to the Steca PRS series
the PR series is equipped with a LCD display which makes it easy to control the device's funtions and shows all current
working parameteres.

Generally the controller is only usable with the following battery types:

- lead-accumulators with liquid electrolytes
- sealed lead-accumulators, AGM, gel
- 12V and 24V consumers, which can be directly connected to the controller (right connection pair)

Protection functions:

- protection from reverse polarized modules
- protection from reverse polarized consumers
- protection from reverse polarized batteries
- prevents from battery charge and discharge
- short-circuit protection on module input
- short-circuit protection on load output
- protection from a to high charging current
- no-load working test without battery or consumer
- current reflow protection
- over/undervoltage protection
- overheating protection
- deep discharge protection
- CE-compliant
