The charge regulator Bluesolar 150/70 with screw connection from Victron Energy is a MPPT solar charge controller with 45 amp maximum charging current for charging 12 V, 24 V and 48 V batteries.
Charging current up to 70A and PV voltage up to 150V. With the BlueSolar 150/70-MPPT charge regulator, a lower rated voltage battery can be charged via a PV system with a higher rated voltage. The controller automatically adjusts to a 12V, 24V or 48V battery rated voltage.
Ultra Fast Maximum Power Point Tracking (MPPT) Especially when the light intensity changes constantly, an extremely fast MPPT controller improves energy yield by up to 30% compared to PWM charge controllers and up to 10% compared to slower MPPT controls.
