mppt laadt niet door en blijft hangen op bepaald percentage, vervolgens de generator aan gezet die wel door laad. Installatie is 6 weken oud, Calcium accu’s 140 Ah zijn 5 jaar oud. 12V, max laadstroom = 40A
gr, john
What batteries are you using? Did you set the correct charge voltages in the MPPT?
Hi Mac, thank you for your fast feedbackI use 5 Calcium 140 Ah.
settings see below, I do not change the standard settings since the installation 6 week ago. The system was well working.
Where are you reading this percentage, does the battery have a BMS or do you use a shunt?
Ok, that uses a shunt.
The problem you’re seeing is because there a different settings set in the system. You need to adjust the MPPT settings to what your battery specs are. This is something your installer should do.
The system was working well for about 4-5 weeks, any idea what causes the issue? I did not make any changes to settings in the MPPT. Another problem is that the installer is 300 km away from where we are with the boat. I see that the max laadstroom is 40A in the menu of the MPPT. Should that not be 4x 40A? There are 4 connected 140Ah Batteries? The selector switch is on position 2
Looking back at the first screenshots i also noticed the PV voltage is pretty low. Charging only starts when the PV voltage is the battery voltage +5V.
What kind of panels are connected?
2x Sunbeam tough 111w
I am charging with the generator atb this moment, would you advise a manual synchronize when the display says full?
Are they in series or parallel?
Can’t hurt but i don’t think it will help.
