We strongly recommend that you incorporate a charge controller into your solar electric system to protect your batteries from overcharging.
Batteries are expensive and hate being overcharged as the electrolyte boils and gives off gasses.
The Solarix models are suitable for charging either 'gel' or 'liquid' lead acid type batteries, whereas the Solsum range is designed purely for 'liquid' lead acid batteries. All models have two small LED's that indicate the battery voltage and the operational status of the system.
