Just had a chat with GeeWiz
The 2400 model has a switch at the back to switch between 10A and 20A. Just check. It should be on 20A, but seems the units are all shipped on the 10A position

i think the 10A and 20A switch is propably depending on your battery setup (thats my guess)

Maybe if your running 2x 60Ah (then 10A is fine)... but for the bigger boys... 2x 100Ah and up .. the 20A is needed.

on 10A your mecer is not going to charge that quick.. so the 2x 100Ah might not be fully charged by the next Loadshedding (if your on stage 3 or something)


Not sure if your battery's might last longer on 10A or maybe even be worse off at 10A ... u never know. Maybe 20A is not good or maybe 20A is better... i dunnno

For the "Mecer 2400VA, 1400W, 24V DC-AC Inverter" - I assume it has 2 x 100 Ah 12V batteries. These will be connected in series. So you effectively have ONE 24 V 100 Ah battery. You want the charging current to be about 10% of the battery capacity. So you want the charger to be set to 10 A.

its 2x 105Ah Energizer Deep cycles. (each one is 12v 105Ah)

Isn't it 24v 210Ah setup when combined??

-sigh-

You need to connect either in Series or Parallel in order to MATCH your battery bank, with the voltage that the Inverter / UPS requires. If you have 12V batteries, and the Inverter/UPS requires 24V, you HAVE to connect them in Series.

Batteries in Parallel has other issues too - they don't charge/discharge equally. There's a pile of things you need to think about, consider, and look at.

Remember if you put 24v on a inverter made to use 12v it will have a smoking death . And an expensive repair bil

How good is the charger in the Mecer 2400va ?

Is it best at 10A or 20A ? (the mecer has a switch to change the charging to 10A or 20A)


Is this a good charger in this unit. Will it not mess my battery's up.

Oh. Yes I also wanted the 1200 .. was out of stock then already (week ago). So I just bought the bigger one. Lots more expensive because you need an extra battery too.
