I have a 180w panel installed and connected to the 75/15. Volts at battery is 13/14 but can I ask if amps should be higher than 1, it’s typically about 0.5. Also I have a sealed leisure battery and on the app the nearest thing in the settings is agm spiral and others are gel and deep cycle etc.. last question- is in settings which algorithm should I use as it’s default set to ‘battery life’ any advice would be great.
Q1. Charge should be able to get higher than 1 Amp but as it seems that you have enabled the load output it makes a difference what loads you have connected and their draw. Just assuming that the voltage from the panel is high enough and that the panel meets the requirements of the MPPT.
How do you measure the charging? Do you know the actual charging?
Try to set load off (Always off) and see what current you get a sunny day.
Q2. When reconnecting the load output again Battery Life would be an OK setting.
Hi @dmin
The AGM Spiral setting is too aggressive for standard sealed batteries. Try the Gel(2), or even the Gel(1). Or create your own, but if you do that, it's usually best to go with the batt maker's figures. And even then go towards the lower end of their recommended range.
Yes, that's all you need to do. Look though at the settings that bob up to see if they're ok for the Duracells. If not, you can change them individually. The selection will then show as User Defined, but you can save them then under your own name. (It's easier to do that that making a post here) :)
That said, I'm not a big fan of paralleling Pb batts. They can get out of balance if pushed hard, although your 75/15 isn't high powered. I'd just ease back to the minimum Absorb V that Duracell recommend. You may want to change the Temp Comp setting too if you can find one for your batts.
