Something like this?the same inverter is also a charger, it just doesnt have automatic changeover.
Get a Volt meter.Something like this?
How do one know when the battery is charged and to what extent though, etc?
see my post hereI think the bug has bitten me...I'm already looking out for charge controllers and a decent solar panel that I can use to help charge the batteries with after LS hits
seen as you like to tinker like i do (i also run 2x105aH big boys on my UPS) is:-
add a proper solar charge controller like this https://www.sustainable.co.za/victron-blue-solar-75v-15a-mppt-charge-controller.html
and a solar panel (i am assuming your UPS is running 2x12v in series for 24v?)
Then add a solar panel https://www.sustainable.co.za/enersol-265-265w-solar-panel.html
Put a simple on/off switch (bedroom side lamp style is easy) between the solar panel and the solar charge controller. Connect charge controller to your batteries.
Now during the day when ESKOM trips you switch off the UPS at the wall and flip the switch to enable the solar panel.
When ESKOM returns you flip the switch to switch off the solar panel and switch UPS back on at the wall plug.
This will now enable your batteries to deplete less and as a result you will also get more life cycles out of your batteries and will therefore save money in the long run
Not sure.What happened?
