Mppt Charge Controller Circuit Board

I have a local made mppt solar charge controller attach with 24v solar panels its working very good since 2 years.

Mppt charge controller circuit board.

Below is the circuit diagram of dspic30f2010 3 interleaved buck mppt charger controller circuit. At this speed i can charge a 500mah in 42 hours or use it to run an embedded micro controller for example the attiny for the mppt controller. Pwm charge controller circuit board features of mppt charge controller. This design is a 20a maximum power point tracking mppt solar charge controller created for solar panel inputs corresponding to 12v and 24v panels.

The arduino tries to maximize the watts input from the solar panel by controlling the duty cycle to keep the solar panel operating at its maximum power point. Mppt solar charge controller is usually used in the off grid solar power generation systems the energy generated from solar panels is a very valuable resource as it is a clean energy type. The battery over voltage is not controlled there is a protection circuit in the battery. 70a mppt charger circuit igbt buck mppt circuit control card supply and drive circuit mppt control card.

Detecting your power needs and delivering exactly what you need is a fantastic work of the maximum power point tracking mppt charge controller. Now i want switch on to 36v 48v. In this video i put together an mppt solar charge controller made by makeskyblue. Hopefully the wind will blow stronger.

The maximum power point tracker mppt circuit is based around a synchronous buck converter circuit it steps the higher solar panel voltage down to the charging voltage of the battery. How can we convert this 12v mppt charge controller to 24v 36v and 48v. The design is targeted for small and medium power solar charger solutions and is capable of operating with 12v 24v panels and 12v 24v batteries up to 20a output current.
