What pin outs are you using for BMS, I suggest you create a new post for this as to keep this post on track with the existing issue

We have had the exact same issue with our first luxpower (no AC), we asked the supplier for our own installer code. From there you get the unit on wifi and configure via the web portal. That was the easiest for us... The settings are a pain to work with the web portal is far more easy to work with. There is good training videos on YouTube for this inverter. Lux power support asked me to ask the supplier to create an installer code. They also shared their code CNBM02 but we didn't use this and waited for our own code to be created

Also here in JHB they use to estimate my electricity readings effectively when it's estimated I would pay up to R2000 more, if it's actual readings then Its in line with what I should be paying for electricity. When they estimate I would call COJ and give them current reading on the meter and they would update the billing a few days later This may not be the case with you but it's my experience

A few things Don't use inverter data to track usage, rather take readings in the morning and the afternoon at the main meter ( the new ones are all digital). Check your inverter is actually powering the loads during the day from PV and Battery, and at night you should allow batteries to feed the house at some point, weather that starts at 6pm or 8pm is up to how much you consume. You say you averaging 8kw from grid meaning your loads on the inverter are pulling 8kw from the inverter I suspect this could be at night ? I would assume so...... That 8kw is for the loads on the inverter and not the geyser and stove which the inverter cannot track as these are not hybrid grid tied inverters like the sunsynk so the inverter monitoring will have no insight on the geysers and stove . Essentially take daily readings from the main meter and subtract 8kw from that, the remainder of that calculation should essentially be your geyser and stove. Edit*** Geyser and Stove

On all our installs the type of inverters we use allow us to change the output voltage, we set the output voltage to what we get from eskom (if we get 230v from eskom we set the inverters to 230v). This way the inverter does not need to step down/up voltages that much. Sometimes the voltage changes during peak times but not much we can do about that. In certain parts of Gauteng we have seen customers voltage from eskom/city power drop to as low as 170volts these areas usually have ongoing power outages and are indicative of a transformer/supply/load issue

They keep tweaking things in the background which is most likely why the intervals have changed. I have see on a few plants we have installed intervals seems to be 3 minutes apart. Majority of my customers are happy with the Sunsynk app. But I personally use Solar Assistant and its more to do with automation and having realtime readings from the inverter.

Exactly my point, this is where you compromise your own safety and your family to save a few bucks. Those skinny DC and AC cables on a 16kw unit makes me cringe. Sad to say we have seen our fair share of these types of installs floating around Even seen Facebook posts screaming non compliance yet they are selling solutions.

A solar installation with panels is a labor intensive job, the notion that demand will bring down install costs is not accurate. Lifting 20 panels onto a roof is not child's play. I fail to see how these kind of installs will drop over time in price. Unless people are happy to pay fly by nights to reduce costs.

Down to an average of 3.4kw per day from Eskom for this month! Currently at 94kw for the month. Seeing the benefit of the Sunsynk now 😎

Seems fair what the sparkies are asking that is what we would charge as an installer, you can't expect the guy to charge you hourly for skills and expertise because in essence you saying that because one did a DB Job for far less then then the same should be expected of a inverter setup. The package by JC Solar has key components missing and any installer who has done plenty installations will know without batting an eyelid the additional components required for the build and this is no fault of JC Solar they are just an online store. Are you going to have it all ready for R700 per hour ? Let's say even at 1k per hour he makes 3k that cost will not even cover the amount we pay our two key electrians who get the job done iunder 4 hours. Most installers/sparkies know the in and outs for putting these systems together which comes with experience if that experience is worth R700 per hour then we in the wrong business. Any good installer will also provide after hours support and will always come back to sort out any issues and fine tuning. Yes there should be a markup on certain items for installers who provide the full solution but not 100 pecent markup. This has to cover the cost of fetching the components, going to an electrical wholesaler to get all the other bits an bobs to make the solution work. Not to mention these costs cover the efforts that installers like us go through to get registered with major suppliers cutting out the middle man (online store) come time for warranty, who is mostly likely going to hit you with a Gazillion questions on how you carried the install with diagrams and pictures to buy time before they actually log the call directly with the original supplier.

Hey Guys Is this the latest firmware ? M 6.0.1.4 / S 1.7.2.4 / C E.4.2.4

This is awesome, this is how COJ should operate. I hope to see the day that COJ allows us to export to grid.

The four geysers are on the essential side of the inverter? They trip when all are turned on at once ? Or can you cycle them to come on one after the other ?

Agreed the new sunsynk system also plays a big part in the reduction of power from Eskom. Before I would turn on the 250L 4.4kw element during PV hours and only turn on the 150l 2.4kw element after the big geyser was hot. Now I can do both at the same time and they draw 4400 watts together. The Kwikot heat pump for the 250l geyser around 1950 watts and the element in the 150l geyser around 2450 watts only heat this once day. The heat pump also allows me to have a more battery by 6am (35 percent SOC, sometimes more sometimes less depends what the family is running in house). Overall the heatpump is gonna save me during the rainy days when no Solar power is coming through and I need Eskom to heat, 4.4kw vs 2kw.

Eventually got down to adding a heatpump for the 250L geyser, eskom usage is now down to 2.5kw - 3kw per day. From my previous 50-60kw this is a big win for me. Heat Pump is a Kwikot HP007, uses about 1900 watts and can heat water up to 75 degrees I have mine set to 68 degrees. It takes the same time to heat as the element in the geyser which was 4400 watts however the element was set to lower temp of 60 degrees. Water is hot in 2 hours sometimes less.

Now to bite bullet and add the third BSL

Hey bud, so glad you sorted it's a pain when BMS doesn't work.

For most people the Sunsynk Logger will do fine, for me I need integration to automate the loads in my house, one of the key components for automation is SOC, my batteries are usually charged by 11am, and I set node red to wait until they are 98% before turning certain things in the house like the geyser etc. Will be working some rules for load shedding soon

I do a backup once a month remove the MicroSD card and clone it. Love real time stats, able to quickly determine how to manage the system when I am away.

The sunsynk platform is on and off, also some times data disappears. Solar Assistant for the win, as long as you backup your data!!!

Sir hoping you never do it yet and you can also a decibel reading from any free app on iOS or Android No rush at all as well

Thanks sir

Not seeing spikes for any of my customers, sometimes we get all zeros could be a bug. I would send an email to sunsynk support as you said solar assistant not showing anything. Did you check your voltages during those times ?

Added a cable for the BSLs and now I can see the total cycles, 1 cycle to discharge and recharge. Hoping when I replace them my beard will be grey or Ill be grey if I replace them sooner than that 😂

any ITS owners willing to please send me a video of their units ? I want to gauge how noisy it will be. I will provide whats app detail via pm if anyone is willing to assist
