Can't Get My Batteries Fully Charged

[inetdog]

New but related problem. As I've been advised to tweek settings here and there I just went downstairs tonight and ALL of the Inverter and Charger settings are defaulted to what appears to be 12V specs based on the Magnum manual. I cannot increase any of the voltages beyond the default values and now my SOC is reading 24%.

Does the system require you to enter an installer's password to open up those settings to override? Maybe the system has been kept "logged in" until now and then it somehow reset and you have to authorize yourself again?

No password is enabled. I can change the voltage numbers that are there but they cap out at the 12v numbers listed in the manual. How is that even possible? Too late to call Magnum now. Hope everything holds until the morning.

I just took a specific gravity and although I need to charge the batteries the SOC doesn't correspond to the voltage reading on the remote which is 23.9 right now.

Arggg... I'm losing my mind.

That's why a IOTA charger is in my lineup of gear, built for one purpose, and no mucking about. It will keep batteries alive, but cannot get a full charge onto them.
Your batteries likely dropped below the auto-detect setpoint for 24V, and your gear reset to 12V.
As to why you can't access the menus, someone else has to help you with that.

I'm just reading in the Magnum manual that the AC Input Amps default is 30 amps.

I take it then you have a hybrid inverter with built-In charger and generator auto start. That 30 amps I bet is th echarger current and is one major problem and why you generator will not get the batteries charged up. Example if your batteries were at 50% DOD with 30 amp charging will take your generator 20 hours to recharge if you turn everything off.

WHAT IS THE MODEL NUMBER of the Magnum Inverter so I can look up the specs?

You have a serious mis-match problem. First thing you need to do to save your batteries is get you a 24 volt 100 to 150 Amp charger and use it yesterday to get your batteries back up. That 30 amp charger is only using approx 1000 watts of your generator 6 Kw capacity. It is a waste.

I just looked at the specs and the chargers on the magnums are generally 100A
The 30A AC is input alternating current

I know this thread is 3 years old... did you ever get the system sorted out?
Also curious as to the exact battery cell model # and manufacturer... as charge controller and inverter charger voltage settings (temperature compensated) need to be set (at battery terminals) for what the battery requires.

Hi need help with solar power light system. Any info would help.
I have 3 panels that go down to a solar controller and then from there to the batteries. The batteries only seem to get to about 50 percent and don't go any higher. I disconnected batteries and had 18 volts on the incoming side of panel. But for some reason batteries only get up to about 12 volts. My problem is the lights are not coming on at dusk like they had been when I first installed.

You dug up a 6-year old post to hijack a thread? your batteries are toast.

Batteries are brand new thanks for your help!!

18v at the controller is enough to charge good batteries.

So we need to know this
What size are the solar panels
How much power do the lights consume at night ( in KWh )
what size are the batteries
