Thanks guys. Appreciate the advice. Will use proper rated cable for the mains input into the inverter. I read in the inverter documentation that the inverter can be horizontally mounted, but should not be mounted on the battery box. Will make a stand/shelf for it.

I have the same inverter, and have it wired into the DB board at my place. It's a manual process, where I need to plug a lead into the genny, start it up, and then change the changeover switch from mains to generator. Works perfectly fine.

Hi all. I've just bought a SunMagic 3.5KVA 24v inverter as a replacement for my old Mecer 2.4kva 24v inverter. The Mecer isn't currently wired into the DB board, it sits on top of the battery box. I have it feeding a multiplug which has a TV, WiFi router and CCTV and my laptop running off it. The mains input feed for the inverter is just plugged into a wall plug. I want to use the Sun Magic inverter in the same way. Don't want to invest any money into wiring into the DB board, as I'm planning on moving out of this home in the next 8-10 months. Is there any danger to wiring the mains input feed for the Sun Magic inverter to a wall plug ? Not planning on using any solar panels right now, just batteries (2 x 12v Revov 100ah lithium units) The output from the inverter will be wired to a multiplug that I can plug my equipment into. The load will not exceed 500-700w of power draw.

The batteries have been installed and in use for about 3 weeks now and they seem to be working fine. They’re charging at the 10A rate, and from the Bluetooth monitoring that I can see, are charging to full capacity and then switching off the charger. For now it seems like they’re working as expected.

Thank you for this explanation. Geewiz was a bit vague.

The inverter is a very basic inverter. The only thing that’s configurable is the charging current. 10A or 20A - that’s literally all.

From what Geewiz said and what I have read elsewhere about the Mecer inverter, they aren’t designed for Lithium batteries and don’t stop charging once the batteries are fully charged. That’s why they recommend changing it to 10A. It’s to protect the inverter not the batteries. it’s been working fine thus far.

Update on this, I went ahead and lengthened the cables on the balancer and installed the batteries last week. Working perfectly thus far. I have dropped the charge setting down to 10A as recommended by Geewiz and the batteries seem to recharge within a few hours between LoadShedding sessions on stage 5/6. Quite happy thus far. Next thing I want to possibly look at is an external MPPT Solar charge controller and maybe a panel or 2 to help charge the batteries. Need to do a bit of research into that. If anyone has done this, please advise.

Hi guys. After a bit of consideration, I've gone ahead and bought 2 Revov 12v drop in replacements for my Mecer 1440w/2.4kva/24v inverter, as replacements for the LA batteries currently in there. Geewiz is selling them as a trolley kit in this exact makeup, so I figured I'd give it a shot. If it doesn't work as I expect it to, I'll have to change the inverter. But if it does, I can use the inverter for as long as it suits the purpose. I've bought a HB11 battery balancer as well as Geewiz have specified that a battery balancer must be used with these batteries. My batteries are currently in individual plastic battery boxes, with the cabling coming out of each battery box, and then connecting the 2 with an Anderson plug, and then going into the inverter input. My question is, can I lengthen the cables from the battery balancer to reach the 2 batteries without any issues ? There are 3 of them, positive (red), negative (black) and the balancing cable (white). I will replace all 3 cables with new ring terminals on the ends to go onto the battery terminals. The other end is a standard green 3 cable plug that goes into the balancer. I've also read that it's advisable to change the inverter charging setting to 10A instead of 20A for LifePo replacements as it's safer for these batteries. Any input on that? That's the only configurable setting on this inverter, there is no setting to change the battery type or anything else. Thanks in advance guys.

Thanks @Milan188 I guess if it looks too good to be true, it usually is.

I’m in the same boat as you are, also planning for battery replacement sometime soon, hope you don’t mind me piggybacking on your thread. There’s a massive thread on MYBB about these inverters and options available for battery replacement, among other things. Many guys recommend that the charge rate be changed to 10A for the lithium drop in batteries. But some have also reported that they’ve have issues with certain brands, and they don’t work properly with this inverter because of the way it charges, or rather, when it stops the charge cycle. Another thing that comes up quite a bit is using a battery balancer to make sure that both batteries charge at the same rate. There’s nothing configurable on the inverter aside from the charging rate 10/20A. Hoping to hear more from some of the more knowledgeable guys.

Hi all Has anyone come across this brand? Probably some generic rebranded import, but the price I’ve seen seems really attractive. I saw it at the China Mall in Crown Mines,JHB. If I recall correctly the price for 150ah Lithium Ion was around R5500. https://suncheck.co.za/product/12v150ah-lithium-ion-battery/

Hi Beckett Did you manage to come right with using lithium batteries with the Mecer inverter? I'm sitting in the same predicament as you are, LA batteries are on their way out after 2 years and lots of loadshedding and extended outages.
