Hello everybody!
Just a little introduction about myself. Im Stijn, 31 years old and Im living together with my girlfriend in The Netherlands (aka Holland). Im a Dutchy so Im not native English speaker, please excuse the English/grammatical errors. Ive got an degree in electronics and Im working as an electronical hardware engineer and design/calculate/draw industrial automation installations. Im also a volunteer firefighter here in our town and like to go scuba diving in the weekends. If there is some free time somewhere in my week I like to build all kind of electrical project, like the one Im planning on doing now.
Im planning to install 9 solar panels on the roof of the garage soon, with a basic Victron based powerwall/inverter for now and expand it in the years to follow (12 panels on the terrace roof, 3-6 on the house roof). For now Ill probably use some car batteries because the Victron system needs a battery to run but the first couple of hundred 18650 are already tested (photo of my testbench below)and I will receive the next 2000 next week. The plan is to build a 14S100P pack in a couple of years and expand it with more parallel 14S100P packs. Building the battery system right now isnt profitable because of the salderingsregeling (google translate says: netting arrangement?) we have in The Netherlands, but this advantage will start to reduce after 2022 and decrease in the years after that (short explanation below in this post).
Ivel posted a detailed plan with schematics, 3D drawings and calculations of the complete planned system very soon and would like to hear your opinions on the system Im planning to build and what can be improved. Especially people with experience with Victron equipment, and people from The Netherlands with knowledge about local laws and regulations. But all help is welcome of course! Link: https://secondlifestorage.com/showthread.php?tid=9673 If there are enough people who want to follow the build I can do some build/project updates, but please bear in mind its a multiyear project.
If you have any questions please ask them and I will answer them as soon as possible.
So far my little introduction haha, sorry!
Short explanation about the salderingsregeling in The Netherlands:
Most houses use smart energy meters which measure the energy used and the energy delivered back to the grid (for each phase if you have a 3 phase connection). Currently the generated solar power is deducted from the used power on a yearly bases. For example, if you generate 1.500kWh and deliver it back to the grid and use 5.000kWh you only have to pay for the 3.5000kWh. So for the next two year I already have a free battery (I still have to pay a yearly fee, like every household). But in 2023 this will reduced to 91%, 2024 82%, 2025 73% down to 0% in 2031.
