Item: Complete off grid, inverter + solar panels + batteries system Age: parts are from 2018 to 2023 Price: make an offer Payment Method Accepted: EFT Warranty: none Condition: used but good Location: Noordhoek, Cape Town Reason: Upgrading to a new system Collection: at my place. Details : The system can produce 27 to 31 kW per day depending on how well you install the solar panels. That's R108 to R123 saved per day, R39,410 to R44,895 per year, using a R4 per kW very conservative figure. - 12x 12.8V LiNERGY 12.8v 200ah LifePo4 Battery 2.6Kwh each (31.2 kWh total). Bought in 2023. 100 cycles. Were R150,000 new. - 24x Canadian Solar panels 270w (6.48kWp in total) bought in 2018 and 2019 still delivering a 100% of their rated power. - 1x Mecer 5 kVa inverter bought in 2019. - Pi computer with monitoring system. - cables, junction boxes, isolators, etc

I had a lot of exchange with the guys building and selling them. Nice bunch. I gave them a go and swapped my AGM for those. So far, so good!

Hey guys. Has anyone heard about those : LiNERGY 12.8v 200ah Drop In Replacement LifePo4 Lithium Battery 2.6Kwh https://www.livestainable.co.za/product/linergy-12-8v-drop-in-replacement-lifepo4-lithium-battery-200ah-2-6kwh/?utm_campaign=campaign%3A+LiNERGY+Campaign+2+(637b61f1c60ca2001ccb517d)&utm_medium=email&utm_source=omnisend&omnisendContactID=62fa62e347c03d001cde085f I struggle to find any review or feedback. I consider them to replace my 16 x AGM Lead-Acid 200ah 12V. Best regards. Linergy_Datasheet.pdf

Thanks for the details.

Thank you. And it doesn't void your warranty, right?

Dear all. I have a couple of Meccer SOL-I-AX-5M inverters in parallels. They used to be connectes to lead/acid batteries. I'm considering upgrading to lithium batteries. The installers I'm in discussion with is saying that the Meccer SOL-I-AX-5M can't deal with the lithium battery controller and that it means using those inverters and lithium batteries will void the batteries warranty. Does that make sense to you? Are they simply trying to sell me a new inverter? Best regards.

Hello, I'll need 2x HA-02 Balancers to balance 2 banks of 4S2P batterie. Best regards.

Hi guys. I struggle to understand my own installation. It's been done in 3 phases. First phase : 1 x Axpert 5 kVa 12 x 270 W PV 4 in series x 2 in parallel = 1 bank of 12 V 200 Ah batteries : 1 x BVM-712 Second phase, upgrade to : 2 x Axpert 5 kVa Third phase upgrade to : 24 x 270 W PV 4 in series x 2 in parallel x 2 banks of 12 V 200 Ah batteries 2 x BVM-712 At the moment, this is the way everything seemed to be plugged together (and I'm no expert at all, hence the struggle) : - 4 in series x 2 in parallel = 1 bank of 12 V 200 Ah batteries is plugged to one of the Axpert - 4 in series x 2 in parallel = 1 bank of 12 V 200 Ah batteries is plugged to the other Axpert - the 2 banks are linked to 1 shunt and 1 BVM-712 only, itself linked to one of the Axpert inverter Does that seems right to you? The 2 batteries banks use a same type of battery but not the same brand. There not in the physical same space for a lack of space where the first bank was.

I have 2 x 4 batteries inside the roof and then 2 x 4 batteries outside on the flat roof. Here is a picture of one of the bank.

Sure! What would be the cost? How many units do I need?

Thanks, I'm looking for balancer ASAP, before it's too late!

I've been on the forum store and can't find those HA-02 balancer. Where do you guys get them from?

Thanks DeepBass9. If I hear it, at least, I won't go in panic mode now 😂

Hey Chris. Thanks a lot. That's a lot of help. Makes you wonder how come installers don't propose it from the beginning! I my case of 4x4 batteries, I need one balancer per group of 4 batteries? Cheers.

Hey guys, I have a 16x 12 v 200 Ah AGM batteries linked to 2x Axpert 5KVa inverters, monitored through a Victron BVM-712 and ICC-Pi. I don't have any battery balancer at the moment. Should I get some? The battery midpoint deviation value seems to increase significantly recently. (see screenshots) Thanks for your help!
