MyInverter

I use Solar assist with my current system this is a snap shot. This excludes geyser stove and other non essential loads. If it provides a better view to assist.

I am very fortunate it is a small hotel Victorn is my budget and the wife said spend what you want to spend but she will use what she wants to use. I am ok with that. I don't want Synsync and the cheaper options if I am going to do it I'm Going to do it Proper. I'm just trying to figure out what I will need in terms of kit.

Hi all, I am busy upgrading my current system and locked on replacing with a Victron. I have decided on Victron Quattro 15Kva, paired to the following (which are already installed to my current system): 33 330w Canada Solar - panels - currently connected in a series of three panels. 3x 10kw Narada LifePO4 batteries. (total 30kw in Dec will add another 30kw) The application will be eventually to be as self sufficient as possible but with the understanding I will always be connected to Eskom. I want to make sure that it always fully utilizes the 33 solar panels where possible during the day for essential and non essential (geyser etc) and if additional power is needed it can blend from Eskom. Haven't decided yet if I want to use the batteries during the no solar period as they now used for pure backup. I have about 3 1/2 years of data on my current system which tells me the following profiles: Highest load (concurrent load 14kw - ACs, geyser etc etc) Average load during "high usage periods" (bathing kids, cooking etc) - 6kw Average load "quiet times" (kids in bed, just watching TV etc) - 3kw The average load (point 3) is high but I have a large home with lots of electronics that constantly run, and some critical equipment that has to be on 24/7. As above my 30kw battery bank was designed to get me from sunset to sun up incase of a significant outage (stolen cables, substation issues you know stuff that happens all the time here in ZA) @ a load of 2-2.5kw. I am a geek by nature so would want as much of the technology as possible (the screen of course) but also the app connection and as much monitoring as possible. Been doing some research and what Confuses me is all the bits and bobs you need over and above just the inverter. Thought I would ask here what would be recommended to add to the inverter for this type of system? I have solar now with the 30kw of batteries (as per above) so this would be an upgrade on the inverter and additional equipment side.

Thank you very much! Are there any pin outs to create my own cable for coms to inverter or USB ?

Hi all, I just bought 3 10K Narada Life P04 batteries. Now have a question on the front there are four connections, of which I know they are for coms between the batteries and coms with a BMS. Front Panel: - From what I understand you connect them for inter battery coms as follows with a network cable - can someone please advise? Thank you for the advise.

Question on this - so are these actually Sonoff devices? Anyone flashed tasmota onto it (can you even do that with these devices?)

Thank you @Boerseun appreciate the time to answer!

So I am running both at the moment ICC and Solar Assistant. Here is my (this is my personal view) findings to date: ICC Solar - Price I can't remember the exact amount but I think I paid $49 via pay pal - No Pi included there are options to include a Pi Pro's Incredible software from a perspective of the developer knowing the inverters correct calculations and displaying the information It has MQTT built in so if you need to stream the values and access them for another system (like me) you can. A use case is I have home automation in my entire house. I use the MQTT values to do certain things i.e. turn things on and off, arm certain parts of the alarm system if loadshedding or the grid drops at a certain period of time. Another use case is if you want to create your own dashboards and work with the data you not stuck in their interfact. They allow you to SSH into the machine (Raspberry Pi) so that you can always make sure packages etc are up to date and because the load on the machine is not high you can utilize the same RPi for other services you might need. Updates are frequent which is great and you can track the updates in their change log which often is over looked by developers and is good info for the end user. Setup is pretty solid You can connect a HDMI cable and you have the RPi Desktop you can interact with Con's They don't have a mobile app they rely on the centurion solar interface which leaves a lot to be desired but this is where the MQTT service comes in to build your own dashboards which is awesome for mobile. Could do better Their support is good, but often you met with a short answer when you seeking more information or VNC to connect which is not always the best answer. Not saying this is a negative just saying spending more time explaining when all one needs is a text answer. Solar Assistant - disclaimer been using it for one week. - Price R799 (as of last week) - No Pi included, there are options to include a PI Pro's Their user interface is far superior and more "modern" Info is displayed in a user friendly way so if you just want to see the important info easy to read this is your option. ICC Solar is more aimed at installers from my point of view. Setup is easy Graphs are done in a great way they using Grafana in the background which is one of the best interfaces for dashboarding. They have a "mobile app" even though its not a true app and is merely a link on your device to the web interface its functional and works great. Support is quick at responding and often answers the question first time round. Con's It's a headless system meaning there is no user interface for Raspberry Pi installed and the only interface you have to the OS is via the web interface solar assistant provides you. No option to login to the Raspberry Pi via SSH to install a desktop interface or update the operating system (for me this is a big no no). No MQTT however I have been told this is coming in an update in the next few months. Could do better: Besides improving on the con's nothing much So having said all that both will give you what you asked for, now its about understanding which one has the better pro's and con's for your senario.

Excellent thank you. Budget isnt and issue when I invest in solar. I should of done it right in the first time and it cost me i.e. going with the lead acid batteries. However I want to move to Li-ion now so looking to see which ones I should be matching with each inverter since I have three APEX FCS-KING-5000W-MPPT inverters. Currently the load I want to sustain during loadshedding etc is around 3kw/h and I want to sustain that for at least 9 hours.

Thank you for the response! So I am using the APEX FCS-KING-5000W-MPPT I have three of them, from what I understand they are PylonTech compatible. Is that correct?

So I am busy investigating which lithium iron batteries to go for of course you have the PylonTech and then I see other brands out there like Hubble (not heard of them) and some others. What I really want is the least amount of issues with batteries and the best performance. The pricing seems to be in the same range with these brands. Wanted to ask out of experience which ones are recommended I would want to go for 4.x KW batteries at a time.

Hi all, I currently have a large investment in lead acid batteries. I want to add lithium iron batteries to the whole system so I can run them down further. I have three inverters I can split the batteries banks around. Just want to ask if anyone has done this if yes how so I can get an idea of what to start looking at.

Hi all, I currently have the following setup: 36 panels producing up to around 12kw (335w a panel). Three 5kw Axpert King inverters running on 71.97 CPU and 02.66 Display firmware. This is controlled by ICC Solar. Attached to this I have 12 695Cz 12V 230ah lead acid batteries The current load that I need the back up for runs comfortably for around 8 / 9 hours (I have a 3500l marine fish tank which eats around 1.2kw/h and the house runs off a server room which has around 900w / 1kw /h usage). This is all good. The plan is to replace all those lead acid batteries with the Pollys very soon. The Question: I am on average producing 8/9kw during winter of PV power however my max load for the solar circuit is around 4kw. So I have a lot of additional production, the full capacity (working on pure numbers assuming all panels are producing full is 12kw). The house avg usage is around 13 -15kw/h. I want to start using more of the solar power to start taking some of the additional load. What additional load are we talking about? All my stoves are gas so it will be things like: Washing Machines / Tumble Dryer (of which is the new digital inverter type so like an air con) I run A LOT of aircons for both heating and cooling so it would be aircons Underfloor heating, of which when I monitor is (using shelly power monitors) and while its heating doesn't spike as much as I thought it wood as I installed "energy efficient" underfloor heating in (for what its worth) I have three large geysers also monitored with the Shelly Power monitors, they pull around 2.5kw when heating. During the day they pull nothing as they all solar but at night they drink electricity. What I am trying to do: How would i be able to move some of the circuits like washing machine, aircons etc onto the solar system to use ONLY solar when available. I don't want it to use the battery at all as this is setup for critical systems in case of no Eskom or solar. I was thinking of using a relay for this and using the ICC Solar software (Home Automation option with the relays on the inverters) to do this but wont this take time to keep switching between solar and grid? What I do want: If there is enough solar power being produced then those circuits use only solar to save on pulling from Eskom as soon as there is not enough power being produced them seamlessly switch back to the grid. What I don't want: Is the switch over between using solar and grid to be turning the appliances on and off while switching as aircons etc don't like this tbh not many electrical appliances like this. Was hoping to get some guidance here on ideas on how to do this.
