Hi Guys
Yesterday I decided to test to see how long it would take my solar panels to re-charge my batteries after use.
Got 320ah solar and 360ah gel batteries
At the beginning of the test (early morning) the MH control panel showed the battery voltatge at 13.1v
I ran my air conditioning for 1 hour
After turning off the A/C the battery voltage showed 12.7v
In the middle of the afternoon the battery voltage had only increased to 12.8v (it was a very cloudy day)
The charge indicator neon on my Victron solar controller MPPT 75/15 controller was solid yellow (not flashing) which shows that its on 'float charge'
I was expecting the reading to be higher, so I attached a multi meter to the output of the solar controller, which showed 13.3V
So I'm wondering why the output of the solar controller was higher than the voltage being picked up my the MH control panel?
Why the solar controller was only showing as 'float charge' when I'd been running the A/C for an hour?
Will the solar panels ever return the charge state to 13v, or will they charge to a lower level than the battery charger would, when connected to EHU?
Thanks
Robert
