In the calculation of the current it is used IMP not ISC. Get the full datasheet for the panel. That photo is incomplete. Technically there is not an issue to have panels with ISC greater than the MPPT current. The MPPT will pull max it could, limiting itself at 16A. The downside is that you...

I am talking about the input values inverter measures (the power on MPPT input, integrated results energy) and the total energy which came out (from inverter or other other energy measuring device like shellyEM). So the panel efficiency/faults and wire loss does not count. It is about using...

Hello I have one SPF5000ES which does not power on if only grid is connected. I mean it does not power on without battery. All functions works properly. (It was replaced in warranty by a new one) I dismantled it in pieces to clean it up from the dust (~20 months of running). I want to find...

I studied the datasheet of spf6000 some time ago. The main differences are: - 2 MPPTs instead of one - 2x16A PV current instead 1x18A(22A) - nominal power 6kw versus 5kw

It is a useless task to approximate the SOC by voltage on LPF. The BMS does its job counting how many energy gets in and out. Also it drops the charging current in 3-4 steps when SOC gets over 91% (tells to the inverter to do so) You can get Pylontech SOC 100% charging even with 50V it you let...

Backup feature was implemented. (create backup in ramdrive and offer option to update/download) Not quite I imagined. https://solar-assistant.io/help/historic-data/backup

Right now I don't have the needed time to do it. Beside, I am not comfortable messing with linux. But I suspect it will be no more needed after the next crash. (when I will regret for not taking the time to root the SA). Thanks anyway for the hints

Too bad backup create/restore feature is not implemented yet

That is also my idea. Use any SA mqtt published values in HA to create all kind of automations

Guys. You do not get it, or I am not aware of what you are talking about. 1. If you are talking about the smartmeters of the electricity company, they have their infrasturcure RF/GPRS/4G/PowerLan to read and configure their equipment. 2. If you have a smartmeter bought by you for datalogging...

Just read the specifications of SA. It supports: Inverters BMS (batteries) The Smartmeter is wired to the inverter. Any values the inverter reports, it has the data from it's own internal measurements and data got from the smartmerer by communication. So you already have the smartmeter data...

I understand. Every manufacturer says to use his device for the purpose it was designed otherwise, warranty out, it will not work as intended (more or less true). My Pi is a Zero2W so there are not too much ressources left. I chose thy variant because it was cheaper and available. The HA...

SA is built in a way that you cannot install a home automation on that machine without breaking it.(probably) Maybe you realized we try to find a way to tap into the system (on our risk) because the developer of SA do not provide login system details, made the bundle to work out of box and...

I think it is more facile on HomeAssistant. I had OH and migrared to HA. But because SA locks some times (it continues to gather data but it is out of network, wired LAN) I may consider to hook up the inverter usb cable directly to HA machine and use some modbus integration
