4. MAXIMUM POWER POINT TRACKERS (MPPTS)

The main reason for using MPPTS chargers rather than PWM is because they are much more efficient.

For example: if you are going to charge a 12V battery with a 100W 25V solar panel, it will charge at 4A. Now,

multiply 12V by 4. It results in only 48W, and the other 50W is lost.

Another major advantage of and MPPT is allowing the solar panels to run higher voltages, which reduces

losses on cables.

Depending on the type of inverter you are using, it may allow one or two strings per MPPT. The larger

inverters, 8kW and above, normally have two strings per MPPT.

Before connecting to PV modules, install a separate DC circuit breaker between the inverter and PV

modules.

To avoid any malfunction:



Do not connect any PV modules with possible current leakage to the inverter. For example, grounded PV

modules will cause current leakage to the inverter.



The open-circuit voltage (Voc) of PV modules does not exceed the maximum PV array open-circuit

voltage. This is extremely important.



The open-circuit voltage (Voc) of PV modules should be higher than the minimum start voltage of the

inverter.
