October 13, 20223 yr Hi All I'm also new I have settled for: Inverter: 8Kw Deye Battery: 12.5kw Felicity Solar Battery Max output: 120amp giving me about 5.7kw backup power. I will add another battery in 6 months to give me 25Kw Backup. I intend to use 160amp from the two batteries to give me 7680watt for backup if needed. PV: 8 x 600w Canadian Solar (4 - SE and 4 - NW) I have an existing setup 2400w (2x 1200 Hoymiles ) 4x330w CNBM & 4x375w Canadian Solar. I will be using the GEN/MI port to integrate this. Load Non Essential: Geyser - CBI Astute Pool - CBI Astute Stove - Electric - I'm keeping it that way. All other Essential load.
October 13, 20223 yr Hi and welcome, it's a nice setup. Was it DIY? Where did you buy the felicity batteries? Do they communicate nicely with the deye inverter?
October 13, 20223 yr Author Yes it's DIY. Installation in progress I'll keep you'll updated with the fun data we all seek from our investments. I got everything from https://www.solarwaysuppliers.co.za/ Paid cash ( I mean EFT) and collected everything after three day's Edited October 13, 20223 yr by Sipproxy
October 13, 20223 yr Author Question 1 : How can I monetise my data? Question 2: How do I keep my warranties directly with the manufacture when these companies cease to exist ? My first panels were purchased from https://www.inverter-warehouse.co.za/ and my inverters from https://ellies.co.za/ other equipment from https://www.solarwaysuppliers.co.za/.
October 14, 20223 yr Thanks I look forward to the pictures. People monetize through vlogs on paying platforms like YouTube. The warranties will depend on each manufacturer, I think pylontech and dyness you register on their website and they send it to you.

Welcome to the forum, and when all is installed may you enjoy the power independence. With two batteries you should be able to set the discharge Amps to 185A to supply full load from batteries.
October 27, 20223 yr Very neat installation Do give some user feedback on the performance of your battery over time. Always informative for other users to get first hand real life experience with batteries outside the marketing hype.

October 28, 20223 yr Very nice. I have a question. Why is that bettery so cheap? Are they 2nd life cells?

It looks like the new 12.5kwh battery is very reasonably priced, the 5.12kwh battery not so much, maybe it is an introductory offer of some sorts.

Their 8,7kWh is also reasonable, but the 5,1kWh is about the same price as others. I would consider them but only for the larger two capacity batteries. Value for the buck in the insanely priced battery market

Value for the buck in the insanely priced battery market Agreed, looks like the shoto is still the battery to beat price wise as far as 5.1kWh range is concerned, but the 12.5kWh felicity is still cheaper than 2 of them, although they are 1C.

Value for the buck in the insanely priced battery market So I did some googling Tons of reviews and unfortunately not many good ones. Batteries catching fire, starting to degrade after 1 year, not making it to 5 years, very poor warranty service. Maybe price reflects quality I don't know. Also I noticed that they weigh twice as much as a Sunsynk 10kw battery so not sure what cells they are using. I would have taken this battery in a heart beat but somehow I'm not convinced.
October 29, 20223 yr The obvious question would then be: which batteries are good then? I've seen bad reviews / warranty issues for many of the brands on this forum.

Always a bad one on a forum. The more of any make in use will fire more problems. But yes using those that work with all makes 24/7 input will give some guidance. It reminds me of my own Solis 4G mini. I have not seen a single person mentioning a malfunction other than wrong setting cause the problem. Does this mean it is the best inverter ever designed 😜😜
November 25, 20223 yr @Sipproxy Very neat job. I am considering the exact setup from solarwaysuppliers. Any comments on the battery, after 4 weeks of usage? @Chris_S The 12.5KWh is LiFePO4, not Li-ion, so not sure the catching fire applies to these. But definitely nervous to purchase without solid reviews.
November 28, 20223 yr Author The system after 1 month has been working well. Just one issuse. When there is no grid and the battery gets to 100% something clicks in the inverter and the load gets dropped. I took a video. https://mega.nz/file/FvZX2bKS#1VDU82Lvf3AbXfCb28_s5C0txfquaqTKWh-oUGRRBkA So when it's cloudy during load-shedding and the battery temporarily discharges and when there is enough generation to get the battery back to 100% it flickers again. Deye updated the firmware that did not help. They asked me to test using voltages instead of the BMS it did the same thing. Felicity Solar said they will check something with Deye and get back to me 1 week later still nothing. Besides that I'm happy.
May 27, 20242 yr Hi, any news update on your system? Did you manage to get everything sorted and how is the battery lasting this far?
