Practical design A precision control circuit senses system voltage to seamlessly connect solar panels, batteries and charging policies for efficient energy distribution. Wide applications Includes a timer function for night lighting, selectable load control modes, and automatic voltage correction to optimize battery health and performance. Data logging The solar charging controller diligently records runtime, fault events and complete battery charges so you can monitor and diagnose system status without data loss. Easy installation Install near the battery to minimize long cable interference, ensure accurate voltage readings and simplify parameter adjustments. Use scenarios - Off grid street or pathway lighting with a built in timer and load options for reliable nightly operation. - Remote cabins, farms or workshops that require battery health management and automatic voltage adjustments. - Small solar setups on RVs, boats or depots where near battery installation reduces cable loss and enables quick configuration.
