Correct Settings with SmartSolar MPPT for Ective AGM DC170S Batteries

Hi :)

Today I installed my first SmartSolar MPPT (100 / 30) and connected it to my AGM batteries (2x Ective DC 170S). Then I opened the mobile app and started with the configuration of the controller. Now I'd like to ask you whether I did well or if I'm just a stupid newb ;-)

First here you can see the battery specification:

In the app I customized the battery settings as follows (simple mode, not expert mode):

- Absorption voltage: 14.90V

- Floating voltage: 13.80V

- Compensation voltage: 16.20V (default value)

The other settings at the battery settings tab are still the default values.

Is this cone well so far? Shall I change something?

What about the setting for the load output? Shall I stay with the mode "BatteryLife"? I use the batteries inside a camper van and got also a alternative power suppliers that are loading the batteries, but I want to maximize the usage of solar power.

Thanks so far! Looking forward to your expert knowledge :-)

Julian

just follow the battery manufactures specs the specs you have imputed are there MAX figures .

YOU DO not use equalisation on AGM or GEL batteries do NOT GO over the Manufacturers voltage settings

If you are in a HOT climate or the room is over 25 deg c then the higher the temp move more to the lower voltage settings, the hotter the area the more quickly the LA batteries degrade overtime.
