Charge Controllers
The main function of a charge controller or reglator is to fully charge a battery without permitting overcharge. If a renewable energy system is connected to lead acid batteries with no overcharge protection, battery life will be reduced as at times the battery will be overcharged, or sometimes over discharged.
Charge controllers are rated and sized to the systems they protect by the array current and voltage Because of light reflection and edge of cloud effect, sporadically increased current levels are not uncommon, so charge controllers should be oversized minimum of 25%, or larger if you think the system may increase size in the future.
There are a range of charge controller sizes and types available, and Smart Energy can specify a controller that meets the requirements of your SPS system.
