Solar controller PWM BL915C 12-24V/30A+USB for various batteries

The BL915C PWM controller allows charging lead-acid or lithium batteries 12-24V with a current of up to 30A and connecting PV panels with an output voltage of max. 18V (for a system voltage of 12V) or 36V (for a system voltage of 24V) up to a power of 360W). and display of operating parameters.


Product parameters:

- PWM solar controllers connect the solar panels directly to the battery being charged, and after reaching the set or given terminal voltage of the battery, the subsequent regulation is solved by pulse limitation-interruption of the current. This happens at a frequency of units to tens of Hz and on some controllers is indicated by a flashing LED labeled "charge" or "solar". Regulators are suitable for panels with the same system voltage as the battery voltage, otherwise losses occur when part of the power is wasted due to inappropriate V-A characteristics of the panel.
