We have a problem with brand new Victron SmartSolar MPPT 100/15.
After a night, when new day powering solar panels and Victron SmartSolar
-the SmartSolar is NOT reaching Float Voltage setting. We have to unplug
battery and solar panel – to brigh it back (Float voltage). Why?
Is there any software bug? or We have a broken SmartSolar?
We have a Firmware 1.50
How many panels? Battery voltage? How are panels connected? Panel VOC? System voltage? Battery type and profile used? You are aware that to start, voltage has to be vbat +5?
Two panels, voltage about 70-80V, battery 24V (27,6V), "user defined" battery preset to: Absorption 28,5V, Float: 28V.
It works good....to the night. When new day is powering on Victron charger, the SmartSolar is charging battery: Bulk, Absorption and Float.... with voltage below the Float voltage setting. Why?
No none could help me at this forum?, so - where should I ask about it? Is there any Victron support contact possibility?
What charging state do the leds on the mppt indicate?
Do the batteries reach the bulk/absorb setting?
Got to give us some system specs or screen shots of your settings and battery page tabs.
Without this,
If you are not getting into float consistently are you certain your batteries are still good?
For 1 day they might seem good but need to have everything be "reset" by unplugging everything and redoing it to appear good again a day later. So that's one possible problem.
The victron techs are not on here except 1x or 2x a week so you might have to wait a few days more for a direct response. Sharing specific details also will help the community help you find an answer possibly quicker.
Hi what batteries are you using. Because 28V float is very high for a 24V system.
