We plan to install 2 100 ft. deicing cables at an off grid solar powered studio. Each cable is switched on by a controller that registers moisture and temperature. At start up each cable could draw 500 watt. I want to protect the system batteries (4 S460 batteries ([email protected])) from being discharged below 30% of capacity. What controller can I put in line to prevent power from going to the deicing cables when battery storage is low?
