My questions relate to setting and controlling the equalisation for the Epever AN series of controllers. I have just commissioned my system and am learning how everything works. The controller does an equalisation on the 28th of every month and the default time is 120 min.
The Trojan data sheet recommends an EQ voltage of 16.2V. This seems very high and I am worried that my 12V devices will be damaged by such a high voltage.
What would be a lower voltage for a flooded Trojan that still gives effective equalisation?
After doing some research I am beginning to wonder whether monthly equalization is really necessary, at least in my case. I have 550watts of PV at 48V and 460 Ah of Trojan Solar SPRE batteries connected as 12V. I have a steady 12v only load (no inverter) consisting mainly of security cameras and a modem/router. I believe my system is somewhat over designed and don't anticipate depleting the batteries very often. Perhaps I should just do a manual EQ every few months by fiddling with the date and timer in the controller.
Thanks

- Can I stop and start the EQ once it starts?
- What happens if I switch the panels off in the middle of EQ? Does the controller keep timing or does it stop and re-start the clock?
- What happens if the PV output is too low for effective EQ during the time period? Does this effect the total EQ time?
