Solar Panels are cheap now, but keep in mind that montage materials are expensive, the smaller the panels the more flexible but also more work!
to calculate your battery size and panels needed there is a nice excel spreadsheet to download in this forum...
Thank you!
Unfortunatedly Must does not reply to support intents!
The pylontec reseller recomends me to buy a different inverter that runs with pylontec
and scrap / sell secondhand the 1,5yo Must crap!
its never colder than plus 10 Celsius here and I am aware of the maximum voltage problem.
160 Volt input is good for 3 panels 72 cells in series, and nearly 60A should be produced by 4 Strings.
So theoretically ina a 3s4p configuratiion that would be >50 Amp >100V over 5000Watt, to good to be true!
I found this cheap MppT on amazon https://amzn.eu/d/7DdsNbj does it serv me for 3s4p poly 230W 36V 8A

watchpower.exe 1.14 on win7 also says 12345678 wrong password on windows
it doesnt find the must PV1800 VHM on com 8 but solarmonitor.exe can communicate with the cable usb to inverter on COM8
The difference between Watchpower and Solar assistant is huge, its like between a Diesel-Polo and a Tesla!
Both bring you from A to B but at a different cost!
The advantage you get from Solar assistant is that all the enthusiasts enjoy controlling the output very hour and that makes them feel...
I have chatted with some guys that take the complete 36V Lithium packs with BMS from 20 brand new Bird Scooters they bought cheap from some doggy gipsy here in Malaga. Similar to this https://www.ebay.com/itm/224949859447 but at 25€ per piece.

Solar Assistant has a power management function?
Interesting, I have AXpert 4
But it only changes the priority, what I want is control multiple SSR switches
as in my understanding a HV Battery will be more likely to brake as it has a lot of relatively small cells in series and the BMS system needs to be specially adopted to that high voltage. If your power demand is not higher than 6000kVA I see no use to go away from the 48V Standard where you can...
dear friends
I need to know what lithium battery can cooperate via CANBUS with my must PV 18-5048Vhm
to use the options 28 (29,30) control BMS via SOC in the Must's Menue
As I understand the SOC Shutoff would be more reliable and effective than a
voltage controlled shut off with no load...
it always will be zero export as an off grid inverter and can run the house with no power line from outside as long as battery or solar is sufficient in SBU mode
I did not connect the cable from pylontec batterie to Must inverter as I was adviced not to, but I connected an old laptop to the MUST PV1800 to monitor and set paramenters.
The cable is a long printercable and you need a software seriell to usb CH340
The only program that recognises the...
the Inverter won't overcharge or unload the battery excessively if user mode properly configured, but with Voltage control you have to leave some security margin to not stress your batteries too much (what is recommendable any way)
In my case the second Inverter AXPERT does understand and...
My 5kW Must Inverter is already broken and for sale, or maybe someone can fix it for me small priced? You can come for a holiday and do it here, have all tools and spares.
Main disadvantage is the low mppt range and bad software but for a boat or caravan it might be good
hello , I know it s 2 years gone but I still have this Problem,
I am 62 and started with Visual Studio Code and platform IO and Github just to get that SOC% into Homeassistant
and control the loads,
any help would be great!
Visual studio is hanging for ever after it urges me to commit!

I don't see any advantage of an HV Battery unless you can build it from semi new rental scooters for very cheap.
The reliability decreases with every cell and every BMS so you end up with a very short life cycle of maybe 3000 loads that will increase the cost.
To increase reliability you will...
Thank you very much for your speedy reply!
I will continue to buy some electricity or / and extend my Solar Production.
We live in Marbella, Southern Spain with 330 to 340 days of sunshine per year and mild temperatures between 10° and 30° Celsius.
