2x Hager-ESS Switches to enabling switching the Grid-feed directly to the sources or via the ESS system
70mm2 Accu cables
Blue Systems DC-Switches to sepperate the Accu-Packs from the DC-Distribution system. Selected these as they can handle continue 350A at 48V and 600A at 48V for 5 minutes.
I would like to thank my Son for the guidance in this project
Hello @PieterD
welcome to our community. Very interesting setup.
I would right have two questions regarding your system:
To be honest, I never thought about buying case and cells separately to build my battery. Instead I just bought stock US5000 Would you mind sharing your motivation to go down that road?
Your Hager ESS-Switches sound interesting. Can you share the model and maybe a picture? What makes such a switch an ESS switch?
I have choosen for buying the cells and case incl. BMS and Balancer sepperatly to safe on shiping cost. The cells where availble for a very good price here in the Netherlands and the Seplos cases were on stock in Poland. As both came in larger quantities from China this saved me a lot of transport cost and the price was based on DDP. So no hassle with custom duties, transport cost, etc.
Concerning the Hager Switch this is the HAGER SFT440 - 1-0-2 quadapolaire 40A-switch. The bust you buy them via Amazon. They are very cost effective there. This switch has three possitions: 1 - Off - 2 suited for switching L1-L2-L3-N at 40A.
Maximum respect, @PieterD . I thought, Iām adventures to build a Victron DIY DESS on my own Just watched the video, what it means to build a Victron System like yours with a DIY battery pack on top. Awesome. Thanks for sharing and for the additional details.
