Thanks @Coulomb, I'm on it.

Hi @Chris Hobson, Thanks for information. I was able to make the changes. I had problems changing program 29. I then discovered you must first change battery type from AGM or Flooded to User before you're allowed to change this value. Also, can you explain the difference between bulk charging voltage and float charging voltage? I still haven't upgraded my firmware because I discovered the installers took the serial to RS232 cables. I have an old Windows XP computer with a serial port, so I'll have to find a cable the next time I'm in town. Thanks! Eric

Hi @Chris Hobson, Below are the codes from one of my units. Thanks!

Thanks @KLEVA. I'll try to understand some of this stuff before changing. @Chris Hobson Okay. I knew there was a magic key combination. Looks like I have 1 - 31, so I'll post that information shortly. It's a relief to know I have a genuine Voltronic. Today's project will be attempting to update the firmware as suggested.

@plonkster Duhhhh........See I told you I was a newbie. Thanks!

Hi Everyone, Thanks for all the great advice. It's a bit overwhelming so I'll start slowly. @Chris Hobson No problem. Medicine isn't always sweet. Lol So, what are CBs? Also, how do I provide the settings of my inverters that you mentioned? I thought that is what I provided with the previous screenshot. @The Terrible Triplett You guess correctly. I'm about 1.5 hours from Central Accra, but even finding the correct parts in the city can be an adventure and very pricey. @Coulomb I started reading about the patches and discovered that I likely have a clone inverter. The P/N is 4KVA-48-PARA-A which I don't see anyone referencing as a Voltronic number. Below is an image of the label on my inverters. Have you heard anyone else on the forum being able to install the patch on an inverter with this P/N? I prefer not to be the guinea pig. Thanks! Eric

That makes two of us Jaco!

Hi All, Thanks for the quick responses. I did some more investigating and discovered that it was me. I had the voltmeter on AC when trying to measure DC. When I switched it to DC the voltage now reads about 12.6 volts per battery and about 50 volts for the entire battery bank. I think it may be running down because we're simply using too much power during the day. I'm including my wiring diagram and also my inverter settings. It would be great if someone can suggest any changes in my settings to ensure optimal performance. I live in the mountains of Ghana and there is no elecricity company here. I'm totally dependent on solar. If the sun is strong we can usually make it through the night without the solar beeping from a low battery. Thanks! Eric

Hi All, I am a total newbie with solar, but because I've been noticing our system going down very quickly lately, I have began trying to understand my setup. I decided to check the voltage of each of my batteries this morning and to my surprise they all are reading about 27 volts. I have two 48KVA-48-PARA-A inverters with the parallel boards installed, twenty 250w solar panels, and twelve twelve Taiyou 12v 200ah Valve Regulated Sealed Gel batteries. The batteries are connected in four in series and then the three series are connected in parallel to create three 48v batteries in parallel. The battery bank is reading 105 volts. I am not sure how they have the solar panels connected, but when I read the voltage with a voltameter at thePV input it reads 125 volts. I just downloaded the WatchPower software, so I'm about to take a look at how the units are programmed. I'm hoping someone can tell me what might be the problem that is causing the batteries to be overcharged and also if the battery bank may be ruined from the excessive overcharging. We had the system installed around August 2017, but at that point there was no parallel boards inside. The company connected the parallel boards in February of 2018. So, I'm not sure if the overcharging began six months ago or a year ago. Thanks! Eric
