Naa, Imma keep the 24V. At least I know it outright die when PS5, Xbox & 58" Tv all go on same time and I forgot the Swamp cooler is still runing type of thing

IE draw over 720W

I'll just have to fork out for 2 x hubbles.

Don't read too much into how you think it works, it could still be charging the batteries with the fan off.

Green led will be flashing if in online mode and charging, will be steady on if float charging

Sure... I'll swap you 4 x 17" (108 SPacing) mag for 2 x Hubble A-100's? :)

Edit: also Hubble's cant give you pretty pictures:

Ahhhh HA with Lovelace looking so pretty - I don't think people understand what amazing capability Home Automation provides...from remote monitoring to switching to security to fun etc etc!

Checking if door's are closed from bed, or Alarm auto arm when you leave "the zone" is enough reason to have it.
Switching on/off plugs/lights remotely is just a bonus.

Edit: This reminds me, need to check bathroom Light. I unscrewed it cause everytime power returns after LS it just goes on, overriding button state. Think I stuffed up a setting in mqqt....

Yeah still need to check voltage and balance but last night after running the inverter till it was beeping which I got around 2 hours 15 mins, but only using a 100w TV and laptop, eskom power came back on but the inverter only charged the batteries for an 1hr30 as the fans stopped. Surely if it should be charging for at less 6 hours, also bare in mind I've set it to 10amp charge so should charge even longer, please advise?

2:30 hours of 130W on a 24V 1440W system got me down to about 12.4V per battery. My 75% did not even go off when power came back.

If Mercer 1440W starts beeping at 2:15 on your usages, something is wrong, or you did not check how much you actually draw?

Edit: Also 5-6 hours is normal as the inverter has a proper charge curve:

Still, everytime the inverter beeps, it means the battery is very low, save your work, and a good chunk of battery life is taken out forever.

Him I finally got to check the voltage of the batteries. The one battery is 13.33 V and the other battery is 13.43 V. Going to now connect jumper cables to try balance them for 24 hours. Your thoughts on the different voltages?

Not bad. Disconnect them and let them rest for an hour then check again before doing jumper cables. If still the same then what is the load you're running?
 
Just copped a cheap 2400VA + 2x 100Ah Visions for under R6k incl trolley - first step is an overnight charge I assume?

Check voltages of batteries incase you have unbalanced batteries. If unbalanced then don't charge, balance first.

They are new batts from Mustek (sealed in box...) and they're installed already haha

You would need to open it up. Nothing destroys a battery bank faster than it being unbalanced. Sometimes being "new" can mean sitting on a shelf for 6 months and the batteries have gone dead. If you're not the DIY type then yeah, just switch it on and charge it.

Good advice, thanks!

Get some voltage displays like some of the guys here have done to monitor batteries. The one on the mecer is not helpful. Don't use more than 50% battery!

What would you recommend I cut the voltage off at? Is there an in-line device I can install to cut the circuit if the voltage drops below a certain level?
