Note: Appliances like Air conditioner needs at least 3 minutes to restart in case of a power shortage occurs
in a way that the power turns off then back on again rapidly (time is required to balance the refrigerant
gas in inside circuit); so in order to protect your Air conditioner, please consult the Air conditioner
manufacturer whether they have already provided time delay function before installing. Otherwise,
Inverter will trig overload fault and shut off its output to protect your appliance but sometimes it is not
enough and your Air conditioner can be damaged internally beyond repair.
Batteries
The unit support 12volt,24volt or 48vlot battery bank. Please wiring battery correctly. Before proceeding,
ensure you have appropriate size batteries for this inverter. The unit can use flooded lead-acid, or sealed
GEL/AGM lead-acid batteries so ensure that your batteries are in one of these categories. PL20
inverter
with built-in MPPT solar controller, for the battery and solar panel connection please refer to figure 2,figure3
and figure4. If with the built-in 48 MPPT 40A solar charge controller, then please configure solar panels
more than 2350W, otherwise it can not reach the maximum charge current, if with the built-in 48 MPPT 60A
solar charge controller, then please configure
solar panels more than 3500W, otherwise it can not reach
the maximum charge current.
Note: if you are using a gel battery or a deep cycle battery, please do not use ordinary lead-acid batteries for
use in solar energy systems. This is likely to damage the lead acid battery or to reach the desired
effect.
The battery must be wired to match with the DC input voltage. Recommend to use battery capacity more
than 200AH .
