SOLAR CHARGE CONTROLLER
Quick Overview:
A solar charge controller manages the power going into the battery bank from the solar array. It ensures that the batteries are not overcharged during the day and that the power doesn’t run backwards to the solar panels overnight and drains the batteries. Some charge controllers are available with additional capabilities, like lighting and load control, but managing the power is its primary job.
A solar charge controller is available in two different technologies, PWM and MPPT. Potentially increase the charging efficiency by 30% in MPPT based product.
SOLAR Management UNIT (ISIU-12/24V-40Amp)
SMU is independent charge controller that has the capability to interface with any existing inverter of any make to convert it into a solar inverter. It also has the feature to disconnect the mains(only if PV is available) when battery is charged up to the boost voltage (selectable),during this time the load is driven by the battery(s) and then reconnect the mains when battery voltage reaches <11.8V.
The current delivered by ISIU is the additive current to battery given along with the normal charging current given by the inverter to charge the battery.
