"Under Voltage Protection" alarm in inverter

[h_1985]

Hello,

I'm testing a solar charge controller - Ateca Solarix MPPT 2010 - and inverter - RIPEnergy JAZ Pro 700 -

on one panel - AlfaSolar 195 Wp Vmmp = 25.06 V Immp = 7.82 A -

Solar charger indicates "charging now" my batteries was very low .... i have two 12 volt 200 Ah in series

After connecting solar charger to inverter ... inverter gives me "Under Voltage Protection" alarm ... i found inverter input voltage about 14 Vdc and

input voltage according to manual start from 20 Vdc

Is that problem from low batteries OR What?

You do not have enough voltage from a single panel rated Vmp = 25.06 to charge a 24volt batter system. You will need at least 34 volts to charge a 24volt battery.

You also only have a maximum of 7.8amps of charging capacity which gets you a C/25 rate (200ah / 7.8a = 25.6h) which is way too slow to keep even one of those 12volt 200Ah batteries happy.

You cannot charge your batteries configured at 24 volts with that panel. End of story.

It takes a minimum 34 to 36 volts to charge a 24 volt battery. You are no where close to that with a 25 volt panel. I am not going to waste my time looking at your Controller specs to see if it is a real MPPT controller or not, but if it is a true MPPT Controller, you could charge one of your 12 volt batteries with that panel but would be painfully slow to the poin tof being useless.

Basically nothing you bought was NOT made to work with each other. Your panel wattage is too low to charge both those batteries, and too low of a voltage for 24 volts. You need to go to the person who told you this would work, witch slap the snot out of them and get your money back. They ripped you off.

This part you will really like. If you hooked up those two 12 volt batteries in series to make 24 volts and only see 14 volts, they are dead and ready to used as Boat Anchors or Paper Weights.

What is required is a minimum 500 to 600 Watt Panel array, with a 20 amp or larger MPTT controller to charge your now worthless boat anchors you call batteries.
