Jixiao@MPPT Controllers -JX220703-05 20A 30A 40A
Solar MPPT Common negative pole charge controller ML24V series for off-grid.
Feature
1. The maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems. The charging efficiency is 15% to 20% higher than the conventional PWM method.
2. Automatic charging voltage regulation function: When there is battery open circuit or lithium battery BMS overcharge protection, the controller battery terminal will output at the rated charging voltage value.
3. MPPT tracking efficiency is up to 99.9%.
4. Advanced digital power technology raises the circuit energy conversion efficiency to 98%.
5. Support charging lithium batteries, gel batteries, sealed batteries and vented batteries, etc.
6. The controller features a limited current charging mode. When the solar panel power exceeds a certain level and charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.
7. Support automatic identification of lead-acid battery voltage.
