“The FLEXmax 100 & FLEXmax AFCI from OutBack Power are the most innovated, advanced MPPT charge controller technologies designed for fault intolerance,” says Ian McCluskey, Asst. Product ...

Diving into the cost spectrum, the price for an MPPT solar charge controller can vary significantly based on its capabilities and the brand. Generally, they range between $70 and $600 .

An MPPT charge controller keeps your solar panels at the ideal voltage and current for maximum power output. At the same time, the controller keeps a suitable charging voltage for the battery system.

A solar charge controller smooths out that variability so that batteries receive power at a constant and safe rate. It also sends a “trickle charge” when the battery is nearly full.

A few years ago, [Lukas Fässler] needed a solar charge controller and made his own, which he has been improving ever since. The design is now mature, and the High Efficiency MPPT Solar Charger is ...

A solar charge controller is essentially a solar battery charger wired between the solar panel and battery. There’re two main types of solar charge controllers – PWM (pulse width modulation) and MPPT ...
