That is why I suggested you should create a separate “WiFi network” / SSID for your IOT smart devices and only turn these settings off for this SSID. These settings are normally configurable on a per SSID basis. Then the rest of your devices can continue as is at full speed on your regular SSID.

I would suggest that both of these gents are on the right track. Most “Smart” / IOT devices only support 2.5GHz WiFi band. If your WiFi devices support this, create a separate WiFi SSID with a name like IOT and limit this to 2.5GHz and turn off all the fancy features. Keep it plain and simple. Then use this “IOT” network for all your smart devices. Easy way to test your heat pump is to create a WiFi hotspot on your phone and see if the heat pump will connect to that hotspot.

+1 for the LuxPower SNA. Rock solid. Full featured, good local support.

I'm no expert, but this is how I understand it. The Sunsynk 5Kw Hybrid as a 13A limit per MPPT. The JA460W Panels are in the 11A range. The JA550W panels are just over the 13A limit of the inverter. So I suspect this would be the logic behind his suggestion. Inverter 460W 550W

@Flouw I was on SA with my previous inverter. I then moved to a LuxPower LXP5K with a PowerGem battery (specifically for the tightly coupled inverter and battery management in a single interface, including firmware updates etc.). Initially I was dissapointed with the low level of functionality / integration of SA with the Lux inverter, but as I got to know the LuxPower management interface, I realised it had everything I needed and some things that SA still doesn't offer (Email and mobile app event notifications). If you want to stick with SA as your base platform, I would recommend looking at a Deye inverter. A work colleague has a Deye with SA and flip it has fantastic integration and advanced automation. Real "if this" then "that" type of logic. I've included some screen shots below that show that you can set multiple time slots for different functions to give you a level of automation (Depends on what you are looking for). The time and effort that LuxPower put into developing their mangement platform is one of their differentiators in my opinion.

Personally I am a fan of the “add more panels to existing setup” option. The additional panels when they are not feeding the geysers can contribute to charging batteries or power other loads. Panels dedicated to geyser loads will sit idle when not needed. Nothing technical in my thoughts, just the way I would doing it.

https://solar-assistant.io Buy Solar Assistant. It is very good. You can buy the software only or preloaded/bundled on a pi (recommend).

Ok. It seems this is a popular topic with historical discussions. Follow the link to FAQ1 in the topic below

My own 2c. I'm on my third ride on the solar merry go round. For the first two iterations, I sourced all the kit online myslef, from the cheapst online supplier. Got my local "traditional" sparky to split the DB and do the cable work. I did the rest myself. This left me with all the management and responsibility of keeping this thing going, working with an original online supplier when there was a problem, shipping boxes back to Jhb, couriers etc. (I'm in Durban). On my third iteration I took a different approach. Instead of researching vendors, brands and products, I reached installers. I found the best rated, most experienced installer possible in my area. Our initial meeting we didn't discuss any products. I gave him a list of my wants, desires and expected outcomes. I left him as the expert to recommend options to me that he guaranteed would meet my goals. Basically after lock down and a big shift to work from home, reliability and uptime was now key, (we had gone beyond a few lights, internet and the TV) post implementation single point of contact support, ease of end to end management / set it and forget. I was tired of becoming the whipping boy for the family everytime the power went off for whatever reason. Long story short, this was the best thing I ever did. Funny enough his actual labour cost was the cheapest part of the solution and really reasonable. Professional install, great personal support response afterwards. He also fixed so many unknown(to me) F@ckups from the previous tradional sparky. His initial product quotes for the inverter and battery were a bit high. I pointed out some of the cheaper quotes online. He negotiated with his supplier and got the costs inline. I would go this route again and again. Cut costs somewhere else but have a professional take you through the design and install. I am a techie at heart and my guy was great, let me sit in on the whole install. Oranised me an installer account for my system so I could still do some of my own advanced configuration etc.

Double check the cable / pins between battery and inverter?

Yup. I look at all the 10 year warranty's being offered with a squint in one eye. Good luck in 9 years, 11 months time. 🙃 But hey, in the short term I sleep better.

100% on the set it and forget it. That’s exactly why I went the “integrated” LuxPower plus Hina route. And it has delivered. Both companies are very active in the software/firmware development side of things. I popped over the the SNA / LXP change log site this morning to confirm. There is a software/firmware update at least once a quarter. I have had two software updates for my Hina PowerGem battery since installed in December. As I went with the LXP model I got the free 10 year warranty extension for both the inverter and battery. This was a nice to have, not essential. They really have put a lot of effort into their management software to the point I have shutdown my Solar assistant. Having integrated inverter and battery management on a single screen just adds to that whole peace of mind thing. Something I did learn in my journey is that in the local inverter/ battery / solar space there generally is no such thing as a single authorised importer and agent for a brand, such as we see in other industries. If, for example, (and I am generalising) you see a battery on site A for R25k and the same battery on site B for R21k, there is a good chance that the cheaper battery is coming from a different route to market. The cheaper option might cost you dearly in the long run.

I know this doesn't directly answer the OP question, but if you are going with a LuxPower inverter then you should seriously consider a Hina (ESS or PowerGem) battery. They have a joint relationship with LuxPower providing integrated software and management. You can manage both the battery and inverter from a single console as well as do all firmware updates etc. The ease of integration and joint management is a blessing. It also makes for easier / better quality support if you have a problem as they run a joint support WhatsApp group locally.

So I have previously moved from Growatt to LuxPower (LXP 5K model). I was also running solar assistant on the Growatt. Solar Assistant does work with the Lux Inverters. It scans your local WiFi network for the LuxPower dongle and connects via the WiFi network. No cables to plug in. Functionality of SA with Lux inverters is very basic. No scheduling or automation etc However the level of management provided by the LuxPower dongle / portal / app is so good I eventually turned off solar assistant. The LuxPower management even has email and mobile app alerting which SA is still trying to get working.

@TaliaB glad you enjoying the batteries 😀
