I need some advice about the system that I am doing. I have:
1 Multiplus 2 48/5000 - ESS
1 cerbo gx at ac in with 12v transformer before bypass point
1 fronius primo 5.0 at mp ac out
1 aftermarket 7” display
1 hager sft440 for bypass
1 10kw battery (waiting for delivery for about 90 days)
Despite not having batteries I started to assemble what I could because I want to do all the firmware updates and cable management ready while I am waiting for batteries.
The doubts are:
As you could see in the picture I could install and update all the firmware, and the system is working with no problems after those upgrades, can I still have this running without batteries while I am waiting or it is better to bypass the mp for now.
About the cerbo gx, I live in a stable grid power area, can I connect the cerbo gx with from ac with a simple 20000mah powerbank with a step up converter that outputs 0,8a at 12v. By the multimeter value yes but anyone tried it?
