and any system errors. Custom icons and back lighting
make the meter easy to read and understand.
- Lower Cost
Two battery charging eliminates the added cost of two separate solar charging systems and the need for isolation separate solar charging systems and the need for isolation
- Easy to Install
The controller is installed near the batteries using the clearly labeled large wire terminals. The remote meter may be mounted in the wall or on the wall using the included frame. Also includes the meter wiring with RJ-11 connector.
