Hi. I decided on the 5kw sunsynk, 5kwh revov and 8x 545W JA panels. Panels are installed but waiting on inverter. It was on back order.

I am planning on using a sunsynk 5kva inverter.

I do understand that and I would have liked a 8kva sunsynk. But they are a bit pricey. One of the issues I have with going the axpert route is battery communication and also not have so much control on saving your battery at a certain SOC for later use ie Loadshedding.

I don’t mind being limited by the 5kw on the non essential side and then pull rest from grid. My plan is not to be off grid. I want to save a few bucks a month and then have a solution for the loadshedding. I want to add a second battery in a years time. That will help to get me further into the night. The geyser will be on smart switch so I can run it during the day and top up from florid if needed. Battery will be for essential loads only.

Thank you for the response. Is it safe to have these systems in the house? My DB board is close to 30m from my garage.

I finally think I know what I want. 1. 8x 545W JA panels (Installed) 2. 5.1 kWh revov r100 or b100 (which ever is available) 3. 5kva sunsynk inverter Now my question is can I export to non essentials without changing prepaid meter. I don’t want to export to grid but want to export excess solar to non-essential side. The reason for that is I want my pool/aircons/oven and geyser on the non-essential side but still use PV during the day to run it so I can save money. Thanks

The installer I am using are getting them for me. The accredited reseller in PE is PIRI solar.

Good day I can get revov R100 batteries for relative good price and from what I read they are rated for a lot of cycles with a 10 year warranty. Any opinions?

So I have a friend with a RCT axpert. He explained that his inverter blends Eskom and PV power fine without any issues. His inverter is the 8Kva hybrid model. Do the inverters trip once you overload or does it go into bypass where it basically just uses Eskom?

Would a 5kva limit me in the sense that I will overload it often? Of with grid being on will I just use pull extra needed from grid. Example load is sitting at 3 or 4 kw and someone puts on hairdryer or tumble drier and load pops to 6 or 7 kw, will the 5kva trip or pull extra from grid? I know when grid is down it will trip. But again when loadshedding hits I want to make sure heavy load items are off to preserve battery. I understand to get it right from the start, but to get 8kva sunsynk and a battery without panels defeats my goal in saving on my bill. I don’t know how soon I will have another 30k for panels. That is why I am going for a system with panels and that is why I am limited by my budget. Paying 100k just for a loadshedding solution is not worth it for me. Some people might be able to save 30k in a couple of months, I cannot unfortunately. Spending 100k I want to make sure of all my facts. It is a big spend for me.

Can afford either 8kva RCT of 5KVA sunsynk with a 5kwh battery and 3.5kwh panels. That is my dilemma that I am sitting with. Get the 8kva and run everything off inverter and run geyser and pool pump on timers for daytime use with solar and use battery as backup and try and cycle it daily to 50% and keep the rest for loadshedding. Or get 5kva and add everything except oven/geyser/pool pump and then export solar to non-essentials. Either way with loadshedding I will have to make sure to reduce my load and usage due to small battery size.

I am from Port Elizabeth. Quotes I got: Sunsynk 8kva R41400 Sunsynk 5kva R25400 RCT Axpert 8kva R25156 Anther quote RCT MX2 Axpert R22000 So many installers advised me to go Axpert due to my budget and then go for the 8kva. They say the sunsynk is very nice if you can afford it.

I unfortunately cannot afford the 8kva sunsynk. But the price for a 5Kva sunsynk and 8kva axpert type is basically the same according to quotes I got. For me it is not a thing about going off grid completely. I want to have a backup in loadshedding and also reduce electricity bill. I am also willing to cut down usage during loadshedding to not overload the system and make my batteries last.

My question is do I go with a sunsynk or Axpert like a Kodak or RCT. Do I need the 8 KVA. I have read that when the sunsynk 5 KVA is connected to the grid it can handle a load of 8000W. And when it is loadshedding it is limited to 5000W. I’ve heard that if you overload the off grid inverter it alarms and trips. I want something that if I overload it, it just pulls the balance from the grid. I am not planning of going completely off grid. So I am very confused on what to do. So many installers and distributors have their own opinion. One saying one thing and another something else.

Thanks for the response. I am in the process of saving some money. Managed to save about 100K so far. So depending on when I do take the plunge will depend on my budget at that point.

Hey everyone I stay in a house that uses around 30 units electricity on average per day obviously goes up when using aircon/tumble drier/ oven etc. I am looking for a solar solution that will reduce my bill but also help with loadshedding. My budget is limited tho. I have around 35 lights around my house/garden/ driveway walls and outside wall which I like and what to keep due to the fact that everything is nice and lit up and it is a plus for safety. I want to leave my electric oven (top is gas) on grid as well as my aircons. Should I change my Geyser to a 2kw element and leave that on the grid or add to my inverter on a timer? Should I go 5KVA inverter or 8KVA? And which one? I was told to get sunsynk but friends told me to go for RCT Axpert 2 and another told me to go Kodak. I have an electric geyser and my budget doesn’t allow to change to solar geyser and I need to get something for loadshedding so that is why I am planning the above. I would like to start with 10 KWh battery but I am sure budget will limit to 5kWh to start off with. Any advice/ideas? Thanks in advance
