Büttner Elektronik solar controller SC330 MPPT (max. 330 W / 30 V solar modules)

High-quality solar charge controller "Made in Germany" for optimal battery charging. MPPT solar controller suitable for all types of batteries. 2 solar inputs also suitable for different solar systems. For example, a Black Line can be connected to input 1 and a Power Line to input 2. Mobile app control via Bluetooth possible and/or a bus display (optional). With charging output for starter battery. Specially developed for use in travel vehicles.

Delivery includes a temperature sensor, so temperature-controlled charging of all battery types can be guaranteed. Battery type can be individually set (liquid/gel/AGM).

Equipped with overcharge protection, on-board network filter and additional charging output for the starter battery. Battery activation program for long-term charging.

Note: All solar controllers are delivered including a battery temperature sensor to enable deep-cycle on-board batteries (liquid/gel/AGM) to be charged correctly; integrated LED monitoring; connection option for MT solar remote display and EBL connection cable set (option).
