Hello Coulomb thanks for your input. Thanks for clarifying the Amperage drop makes sense. Will see if it does change it back to 30 in the morning but if i dont manually change it to 30 in the morning the battery never gets charged by the end of the day. Its become a routine for me to change it in the morning. Will leave it tomorrow. Just for interest sake , the battery was fully charged at 12:12:47 pm today. From there it remained on inline mode. I did discover if i switch the Inverter completely off for a min including disconnecting the battery, and solar panels. Then restart everything the system will be stable for a couple of days then start the reset thing again. Ag well guess i just got to live with it. Thanks you for all the feedback.

Hello there. The inverter is about 4 months old now but the supplier has ignored the last 3 emails i sent to them. I can live with all the other problem but then i have to manually tell the inverter to switch back to Batterymode at night because the "Back to battery voltage" gets reset to 87volts(Like i said before its not a typo.) I did ask the supplier the first time please send me a firmware update but nothing has come of it. Just another case of bad service here in our country thats why i was hoping i could get help from here. I will just have to wait till there is a firmware version for the VM III available then. Thank you in advance.

Hello Coulomb Yes i will be upgrading to a second battery soon but the Inverter resets completely. I understand the charging rate drops to lower amperage when battery is nearly full. The problem is the inverter resets itself on a daily basis. So it needs to be reprogrammed all the time. Back to grid resets from 48 to 46Volts, Max Charging current resets from 30 to 10, Battery cut-off voltage resets from 47 - 46, and Back to discharge resets from 53 to 87Volts, yes 87 not a typo. The battery never disconnects because i never pull more than 450Watts on battery mode. So the battery lasts for about 10 hours on average after a full charge. and i never get a error saying battery connection lost. Even in the logs. But the logs give no errors on the reset thing either. so once it resets the solar does not charge the battery with more than 10amps and then never returns back to battery mode when it reaches 100% Charge so i have to manually put the inverter and reprogram it to SBU mode daily. and make the charging amps 30amps in the mornings. I work from home so all power hungry appliances run during full sun hours hours of the day but then i am on utility mode in any case. as this happens when i wake up in the morning and switch the coffee machine on the battery although still fine the voltage drops a bit then switches to utility mode. I know these inverters reads the voltage wrong but i am fine with switching to utility mode in the morning. But in the afternoons when all business Computers get switched off and sun goes down i have to then go back to the laptop and reset the inverter so it goes to SBU mode although the battery is normally fully charged at around 2pm daily. Sorry long explanation. That is if i remember to reset the charging amps to 30 again in the morning. My average usage on battery mode is about 200watts. The 40"LED tv internet Fiber router, Rasberry Pi for streaming and LED lights in the house. I dont run decoders or overly power hungry devices. We live a simple life. There is days now in winter that the battery does not charge fully but thats why i will also upgrade by adding another 2 405Watt panels that will bring the charging times down a bit plus give the system an extra boost when i need it. Geyser is solar so no electricity there and stove is gas, also use a whistling kettle to boil water for tee. Washing machine is the only electricity hungry device but that always get run in the mornings on utility mode. We try and do washing as soon as we see the battery is charged then all the solar energy can go to the house. Anycase was hoping someone would have a firmware update otherwise its already just become a routine for me in the morning to reset charging amps and then in the afternoon go back to the laptop and switch to SBU mode again and reprogram everything. I feel its just should not be like this. Thank you

Any assistance will be greatly appreciated. Hello Everyone. I have a strange issues on my inverter and now the people i bought it from is also ignoring my emails. See email bellow. Its stable for a week or two then it will do this strange behavior for a week or two. it goes in circles like this. I asked the people for a firmware update as i am sure its probably just a bug or something but everything is now being ignored.____ I have a 5Kw III offgrid inverter.Please see images attached. I just want to know if there is an firmware update on it because I have to reset my inverter every other day. I also have to reprogram it basically every afternoon because it charges the battery but then does not go back to battery mode. So I have to log on to the software and apply settings every day. Really every day. It also then resets the charging mode to 10amps and makes the battery voltage to go "back to the battery mode 87volts". So it never switches back to battery mode. Always stays on bypass mode. This is really frustrating and makes the system unreliable. I am running a Pylontech 3000 battery on the inverter. The inverter is about 3 months old. If anyone can give me some decent advice on how to sort this it will be greatly appreciated. I have 4 X JA405Watt Mono Solar panels in series - Average is only 1200Watts short spikes to 1600Watts now in winter. 5KW Inverter VMiii Pylontech 3000B battery connected via RS232 port to the Inverter. Yes in communicates correctly. We very light users when it comes to electricity so this is more than enough for my house. I might get another 2 more panels to push on the average watts to 1800Watts just for an extra boost when needed.
