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.
Cn3722 solar panel mppt full sun.
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.
In previous videos i ve been able to recommend so.
They convert a higher voltage dc output from solar panels and a few wind generators down to the lower voltage needed to charge batteries.
Batteries or lifepo4 batteries with constant current and constant voltage mode.
Maximum power point tracking function.
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.
I ve been trying to find the cheapest solar charge controllers the internet can provide for a little while.
Fidgetgear cn3722 mppt solar controller 3a 2s 3s 4s lifepo4 cell or lithium battery charger 3 0 out of 5 stars 1.
The cn3722 is specially designed for charging 1 or multi cell lithium ion.
The cn3722 note 1 is a pwm switch mode battery charger controller that can be powered by photovoltaic cell with.
