Hi! We are planning for a grid-connected solar panel system with battery backup. Either with Multiplus or even a full ESS system. But what version of Multiplus?
Can someone please advice what version of Multiplus (MP or MP ii) are accepted to install in Sweden without external anti-islanding equipment. I have found certificates talking about other European countries but please if you know guide me to the right solution for Sweden. BR Tomas F.
My electric companys technical conditions (GEAB) specifys to comply to SS EN 50438
wich Multiplus II states in its declaration of conformity
(seconds to last on https://www.victronenergy.se/inverters-chargers/multiplus-ii#certificates ) it do comply to.
So if i read and understand it right the Multiplus II will work and be OK to use in Sweden whitout any other anti-islanding equipment.
I will, soon i hope, ask my GEAB if i can install 3 Multiplus II in my house.
How is it going? I´m also trying to get it straight with GEAB, did you get an answer from them?
Nope.. asked my electrician to get it all started but he´s not that good at solarinstallations so i guesss he have not asked GEAB about it yet.... Guess i have to do a AC-coupled installation whit a small fronius and the Victron-stuff "behind it all" by myself to get the functions i want... ALL the electricians i have talked to about this just back off... they are NOT willing to do such things ... and to find a "victron pro" to install seems even harder to find..
The Multiplus II has internal anit-islanding relay already. but you need to find out from your power supplier as to what approvals are required, these are all listed on the spec sheet for the Multiplus II
Many thanks for your reply. I will phase the question much clearer: The datasheet for Multiplus II states a lot of standards that this machine fulfills for anti-islanding. But the datasheet for Multiplus only states "See our webpage". That standards for anti-islanding do Multiplus fulfill? (Or please show where on the Victron homepage this is listed.)
Hej @TomasF, @ehsab och @kjell , jag har som tanke att sätta upp ett par paneler
på taket -> MPPT -> Batteribank 24v. Använda mig av MultiPlus som har AC IN.
Två frågor:
1. Är det möjligt att konfigurera så att strömmen dras från batterier först och sedan när de har tömts ur till den nivån jag har ställt in så aktiveras AC IN igång och förser mina prylar med el tills dess att batterierna har nått upp till en viss nivå igen (med hjälp av solceller). Då stängs AC IN av och strömmen tas återigen från batterier.
2. Går det att "stänga av" så att det inte skickas ut något på elnätet?
Hälsningar
Andreas
