The SY3024H PWM controller allows charging lead-acid batteries with a current
of up to 30A and connecting PV panels with an output voltage of max. 25V(12V) or
50V(24V) up to a power of 360W(12V) or 720W(24V). It is equipped with an LCD
display for setting and displaying operating parameters. PWM solar controllers
connect solar panels directly to the battery being charged and after reaching
the set or given battery terminal voltage, subsequent regulation is solved by
pulse limiting-interruption of the current. This happens at a frequency of units
to tens of Hz and in some controllers it is indicated by flashing of the LED
labeled charge or solar. The controllers are suitable for panels with the same
system voltage as the battery voltage, otherwise there are losses when part of
the power is wasted due to the unsuitable V-A characteristic of the panel.
