So the last post was on May 15 2024.....is this because we do not have loadshedding,....or am I missing something? Just curious

Yea like wingnut said the market has moved on

Once you buy a battery/inverter it just makes sense to buy something that can handle panels

And also when the stages went higher devices with quicker rates started to take the spotlight
 
My two Mecers have been feeling very neglected lately. So I did an earth leakage trip test, which tripped the power, and they kicked into life and they were happy. I turned the power back on and said "Well done, guys, now back to sleep". I guess they'll be OK - I hope so.

LA or LFP?
 
Is there any videos/threads or tutorials on fixing the mecer modified sine wave inverters? Assume its the mosfets that needs to replaced.
 
Hi all,

More than 170 pages here, difficult to sift through them all.

I had a Mecer 2400 - it blew up recently. Pop and smoke. Research tells me not to bother trying to repair.

I have 2 x 12V 105Ah deep cycle batteries. I only need to keep my router, Nvidia Shield, a Lenovo ThinkCenter mini PC (machine only - no monitor) and a 65" TV going. If things go on too long everything else gets switched off expect the router.

Please advise on suitable replacement inverters to consider, for my setup and requirements.

Thank you very much.

^ how old are those batteries and how long do they last these days with that load ?

They're about 30 months old. Possibly cycled 10 or so times. Before the mecer packed up, I'd get around 14 hours to 50%, but that was some time ago as that length of time without power is rare.

Happened to a client as well, they are on their 3rd unit, 2nd unit was DoA, now this one is dead within 4 months. Luckily Mustek have fixed it under warranty.

Might have been a surge but it looks like these units aren't very robust, you get what you pay for I guess.
 
So now that we don't have load shedding what do you do?
Do you keep it plugged in or disconnect everything.
What is best for the battery?

Keep everything as is, if you have lithium reduce the full charge to at least 70%, they recommend 50% but just in case something happen and you need them.

I use Sonoff to cycle mine, they are connected to 2x100W solar so I have set some schedule for them to run during the day, still need to perfect it because I end up having to recharge through Eskom at times.

Thanks. This is the Mecer thread. Can you select to what percentage your batteries are charged on a Mecer? And I just have a normal 200AH lead acid battery.
I have it switched on at the plug, but the switch on the unit itself is off, thus it will not draw from battery when power goes off.

yea with the lead acid you have to make sure it doesn't discharge and spoil the battery
and since lead acids love self discharging
so keeping it plugged in it will float that battery constantly and keep it from dying

with lithium a person can switch it off at the plug and every few months just do a top up
like once a year imo
