Cn3722 Solar Panel Mppt Full Sun

Batteries or lifepo4 batteries with constant current and constant voltage mode.

Cn3722 solar panel mppt full sun.

Searching for a compact mppt to use in our soln1 panel we ordered the 2015 new 18vdc input 2 4 series of lithium iron phosphate lithium battery charger 12v charger mppt solar controller cn3722. Fidgetgear cn3722 mppt solar controller 3a 2s 3s 4s lifepo4 cell or lithium battery charger 3 0 out of 5 stars 1. Maximum power point tracking function. They convert a higher voltage dc output from solar panels and a few wind generators down to the lower voltage needed to charge batteries.

Mppt or maximum power point tracking controllers are far more advanced than pwm controllers and enable the solar panel to operate at its optimum voltage for maximum power output. Using this clever technology mppt solar charge controllers can be up to 30 more efficient depending on the battery voltage and type of solar panel connected. A mppt or maximum power point tracker is an electronic dc to dc converter that optimizes the match between the solar array pv panels and the battery bank or utility grid. By connecting a solar pannel and measureing the input voltage to the desired level usually 18v ish but depends on the solar pannel better to do this in full sun when the open circuit voltage is at its highest then.

The cn3722 is specially designed for charging 1 or multi cell lithium ion. I ve been trying to find the cheapest solar charge controllers the internet can provide for a little while.
