Mecer 2400VA Inverter (Community Support)

Good morning all.

I don't know if someone has the same issue or if it has been discussed before.

I have the Mercer 2400 VA inverter with 2x 100ah 12v Gel batteries. The batteries lasted well for about 3 months then gradually they started to fade. The battery percentage indicator will drop to about 25% then the inverter will switch off. After load shedding it will immediately be back on 100%.

Edit: The system now barely lasts the full 2 hours of load shedding @ only 300watts of power drawn from it during load shedding. TV and Router connected.

Yeah,
Lead Acid (ie: Gel/LA/AGM) is not made for our level of load shedding. So suspect em batteries are shot.

They meant to slow charged to 100% for 6-8 hours before being used again... You could try and get them reconditioned or buy new or simply try and find a LiFePO4 alternative that is better suited for SA load shedding.

Yup if you're going to go lead acid, you may as well just get the cheapest, gel isn't superior and yeah that sounds about right sadly I got rid of 4 gels in May. A scrap metal guy came, gave me R5 a kilo for them.

Thank you. Pretty much what I figured was wrong. Just shows yet again. Trying to save money by buying cheap is going to cost me. Thanks for the quick response.

Edit. Will I need 2x LiFePO4 batteries since they are only 12v each and the inverter is 24v?

Step 1: Check to see if the batteries are balanced (are the voltages equal) by measuring each with a multimeter.

Gel would have been ok for 2011-2021

2022 is a whole different kettle of fish.

Correct 2 x 12 in series, you could also try and source a 24V

I'm using this one on my 24V Mecer.

Yup, gel doesn't like being overcharged or undercharged, basically treat it like a Mogwai and you won't get a Gremlin

I believe Scott did do another round that would arrive around january
 
Do you guys mind if I use affiliated links to Geewiz products I personally (or my staff or friends) use related to my reviews?

The extra points will help me get a pure sine faster-ish.
 
Is it "Plug and Play"
Meaning is it a simple swop out (removing lead batteries and replacing them with Lithium ones), no need to change anything on the 'charging settings'
Sorry I do not have the unit so I don't even know if there is a 'charging setting'

Well point A they not meant to use LFP's but we kinda "hack" it as to not use the 20A charge setting.

LA's low V < LFP low V

So sometimes the Inverter switch to float without fan running and 20A is just to much current to handle without a fan running.

TLDR: just drop in but use at own risk.
