Im still trying to get my head around whats wrong with my setup.
i have 1200w panels on my roof, then to mppt and to deep cycle battery., panels in parallel
The battery runs garden lighting during the night, they are on a light sensor and turn on automatically.
my issue is my panels only show 20 to 22 volts, but i only get 3 to 4 amps, even if the battery is down in volts to say 11v
Today is overcast and its 17:00 and i have 22v and .6 amp into mppt and its putting out 14.4 and 1 amp
i have led lights in the house when the power goes out connected to the battery, when i turn them on, the output volts change ro 14v and i am getting 2.4 amps in.
i realize i am drawing more due to the lights,
my input amps from panels goes from .6 amps to 1.7 amps.
more draw on the battery the more the panels produce ???
my issue is at night im drawing a lot from my batteries, but my system still only dribbles the amps in during the day, this eventually drains my battery.
how can i force more amps into my battery to charge it up more, the panels are obliviously capable of more, the mppt just isnt putting enough amps into the battery.
i would expect it to input a lot more amps then as the battery is charged it will drop off.
have i missed a setting on the epever tracer mppt?
if im wanting to charge the battery better do i need a dc to dc battery charger?
