Coulomb......that is why i now have no multi meters.....both in bin. I always buy the cheap once because it is just there to do odd checks. I will look at something better.

Coulomb and Gerrie, Thanks for all the effort and feedback . I had the installer to help and found that one battery is a problem but the biggest error of it all is my multi meter, now called my ex multi meter. lesson learned, get a second tester to verify the readings.

Good morning Gerrie, Thanks for your feedback. I suspect that my inverter has a problem. After i took the photo, i changed the output source to utilities, allowing the system to charge the batteries to full, according to the inverter reading. Battery Capacity was at 100%. Take note that it was fully charged from the solar and was drawing feed from the batteries for about 30 minutes when i took the photo. I then proceeded to disconnect all banks from the inverter. The readings varied between 45.3 to 45.7 volts, per bank. This indicates to me that the inverter is not reading the true volts of the batteries. I will call my supplier / installer today to help investigate. I would appreciate any further advice.

Gerrie, I used 2 different multi meters. I disconnected each bank and remeasured them one by one and the results stay the same, average of just over 7 volt difference between what inverter reading is and the banks. i connected each one at a time to the inverter and the problem still persist. I restarted the inverter and still same results.

Good day, I need advice regarding the battery volts reading my Mecer 5 KV inverter shows and the actual battery bank reading i measure with my multi meter. There is almost a 8 volt difference. This will surely harm my battery banks. I did reset the mecer settings to default, no difference.

Francois, I tried that with no success. it seems that i do not download the correct version. Last time i lost all my data. Surely i do something wrong. What site do you recommend?

Good day, I am using Watchpower and want it to auto update online but i get the message "unable to connect to the network". The PC that i use is fulltime on the internet therefore i do not understand how it can give me this error. Is there any settings that i should set to resolve this error. I appreciate the help. Ernie

Coulomb, Thanks for the feedback. one bank(string) = 4 x 230AH deep cycle batteries in series, this give me in total 16 modules so if I understand your feedback correct then I must not go more then 30Amp setting Thanks for the feedback. Ernie

Good morning, I have been scanning the feedbacks for advice on my charge rate for my system, but I am still not sure what the correct setting is for charging my system. I am using a Mecer 5KVA inverter. 48V I have 4 backs of batteries 230AH How do I calculate what the max charge must be for the banks. I know it must be 10% x 230 = 23amps for a battery on it's own. In a bank I believe it should be the same, but what about 4 banks? Does it split the amps by 4 when charging? is it 4 x 23 = 92Amp? May you have a great day.

Thanks Coulomb for the feedback, Yes it is a 5KVA 145v inverter Now I can stop stressing as my panels is set in a S2 configuration.

Good evening, I have 16 panels with 8 strings of 2. I want to know what PV volts is the most effective for the Mecer 5KV? Should it be close to the max , meaning using 3 in a string, giving me 96v. I would appreciate some advice. Thanks. Ernie

Good day, I have replaced my pc that monitor my solar system. I installed watchpower on the new pc. My questions are How can I get the history data that has been logged by watchpower, on my old pc, to my new pc so that I can still view the stats? Where does watchpower save this data and what is the file called? Thanks Ernie
