Thanks for the advice. This is the way I check if the lithium is charged: First I checking first there is no big load to the system. There is a small display in over the battery with % state of charge and together with that I check battery voltage on a controller depending the time of the day I...

Hello to all friends, thanks again for taking the time to read. I have news again, I installed back PWM controller. After trying all the options of the MPPT, decided that for what I need from the system was better back to 12 Volts and PWM. Now is two days since I made the change and I'm not...

Thanks for the post. Here are the settings. I'm testing the system for a few days before I decide what to do. Since I change the Float Voltage to 13.8 thinks are better and I saw for the very first time yesterday the battery showing 100%, I was not in the van during the day. I almost never saw...

Thanks for the links. The 300 Amp battery got a small display with %.

I checked it now, boost was 14.4 Sorry my mistake Float 13.8 Boost 14.4

Hi. Is 220 Volts here.

I use it more that the Gel battery but turn it off at some point (60% normally).

Dear friends, thanks a lot for taking the time to read and for all the help. I have news, a few hours ago I got the Wifi unit to configure the Epever Controller, after some hours of fighting to connect and then make it work for sufficient time. I did manage to read quickly the parameters of the...

Hi. What I do is I try to reduce the use as soon as it start to go down keeping the eye on the % screen of the battery not to less than 60% then stop normally. It depends of course what electrical devices I will need to use each evening...

Thanks for the suggestion. These are the parameters for a Gel battery according to the table that I'm planning to use for Lithium (presets cannot be changed) Equalize Charging Voltage: NO Boost Charging Voltage: 14.2 (boost Voltage is lower than the recommended for lithium) Float Charging...

Yes, the AC is a very small 300 Wats. unit. The compressor is running all the time (it does not depend on heat) and it is demanding no more than 30 Amps together with computer and lights I know because I check all the time the PWM controller and turn it off the AC everyday as soon as it began to...

Thanks a lot for taking the time to answer, I really appreciate it. It looks to me that the old configuration was doing better, I'm suffering now for lack of power to run the small AC. I run towards MPPT and Serial panel connection too fast. Tried to read as much as I could but didn't find a bad...

Greetings I recently made a controller and battery upgrade from PWM and Gel to MPPT and Lithium, but I’m a bit disappointed by the poor performance of the MPPT controller and I need help please, it hardly reach the Float Voltage when in use and never the Boost voltage neither. I use a day...
