Home Guard Charge controller uses PWM charging Technology, so that as the battery reaches full charge, the PWM pulses slower, gradually tapering off the charge. Pulsing is good for the batteries since it gently mixes the electrolyte, preventing stratification and sulphation. Low voltge disconnect protects the batteries from severe discharge by shutting off loads before the battery voltage drops to damaging levels
Temperature compensation adjusts the set point voltages according
to the ambient temperature. |
- Excellent charging algorithm
- Temperature compensated set points
- Adequate protections and indications
- Negligible voltage drops
- Negligible self consumption
- Offers long life to batteries
- Non-corrosive terminals
- Compact in size and easy to install
