Looking for some expert advice please (for Neil) - hoping Phil might have some insight.
2012 Bailey Approach 620 SE. Battery Master fitted.
Victron Gear:
2 x Ecotree Lithium 110ah batteries
1 x Victron 1P22 mains charger
1 x Victron MPPT solar charger
1 x Victron shunt
1 x Victron B2B charger
1 x 120 watt solar panel
We mostly use hook-up at a site or move on from free sites after a couple of days at most. Very low electricity users, 2-4 hours tv per night, all lights in van are LED. The lowest state of charge after a night with no hook up has been 92%. Reaches 100% after about 1 hour of driving.
Using the Victron Connect app, I checked the shunt history and noticed that the maximum voltage recorded was 14.67 volts. Was advised that this is a little high and to reduce it 14.3. Went into settings and found that the maximum voltage was correctly set at 14.2volts. I was also advised to ensure that the Mains charger and the solar charger were both set to the Lithium battery settings which they were.
In order to set a new baseline I deleted the shunt history settings. These now show the maximum voltage is back around 14.2v. However, the solar charger history settings show that the maximum voltage is frequently at about 15v and up to 15.33v. These readings are not recorded on the shunt history.
Concerned about these high (15v+) voltages, I have done the following:
1. Ensured that the absorption duration setting is set at ‘Fixed’
2. Reduced the absorption time is reduced from 2 hours 0 minutes to 1 minute.
Thus when the solar has completed Bulk charging, it moves to Absorption for only 1 minute before Float stage.
Do you have any idea what the cause of the high voltage readings are on the solar history and is there anything else I should do, check etc ? We are back in the UK in mid-March. Currently in sunny Spain.
Thanks for any help.
