Solar charge controller SRNE MPPT Gen4 DM120
The benefits
- With MPPT technology, the controller has higher response speed and tracking efficiency, significantly improving the efficiency of solar panel energy use.
- Works with both GEL (lead-acid) and lithium batteries; operating parameters can be set by remote control.
- Temperature compensation function and multi-level constant-voltage charging for lead-acid batteries.
- Control of charging power and time.
- Protection and adjustment of battery charging and discharging temperature.
- Intelligent power mode:
- Charging power can be automatically adjusted according to battery level.
- High-precision digital control algorithm for boost voltage and constant current: ensures high efficiency and constant current accuracy.
- Protection against reversal of battery/PV electrodes, protection against short circuits, open circuits and limited LED power, etc.
- Infrared remote control: enables parameter setting and status checking.
- With a metal outer shell and IP67 waterproof rating, the product can operate properly in a variety of challenging situations.
