Off Grid Solar Battery Charger 48v Controller 20 Amp 3 Years
Warranty
12V/24V/36V/48V 60A MPPT solar charge controller
1. With the advanced dual-peak or multi-peak tracking technology,
when the solar panel is shadowed or part of the panel fails
resulting in multiple peaks on the I-V curve, the controller is
still able to accurately track the maximum power point.
2. A built-in maximum power point tracking algorithm can
significantly improve the energy utilization efficiency of
photovoltaic systems, and raise the charging efficiency by 15% to
20% compared with the conventional PWM method.
3. A combination of multiple tracking algorithms enables accurate
tracking of the optimum working point on the I-V curve in an
extremely short time.
4. The product boasts an optimum MPPT tracking efficiency of up to
99.9%.
5. Advanced digital power supply technologies raise the circuit's
energy conversion efficiency to as high as 98%.
6. Different charging program options including those for gel
batteries, sealed batteries and open batteries, customized ones,
etc. are available.
7. The controller features a limited current charging mode. When
the solar panel power exceeds a certain level and the 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.
8. Instantaneous large current startup of capacitive loads is
supported.
9. Automatic recognition of battery voltage is supported.
10. The controller employs a built-in over-temperature protection
mechanism. When temperature surpasses the set value, the charging
current will decline in linear proportion to the temperature and
discharging will be halted so as to curb the temperature rise of
the controller, effectively keeping the controller from being
damaged by overheat.
11. With the help of an external battery voltage sampling function,
battery voltage sampling is exempted from the effect of line loss,
making control more precise.
12. Featuring a temperature compensation function, the controller
can automatically adjust charging and discharging parameters in
order to extend the battery's service life.
13. The controller also features a battery over-temperature
protection function, and when the external battery temperature
exceeds the set value, charging and discharging will be shut off so
as to protect components from being damaged by overheat.
14. TVS lighting protection
