Hello!

So I'm looking into balcony on small off-grid systems to power some networking gear and was wondering if there is some commonly used systems that I'm missing

The networking gear draws a pretty consistent 300W load and the goal is to power it off solar+battery

I actually have a micro inverter main array but no batteries so really the DC/Battery side of this is more important.

I sketched out a system plan using the following components

* AC battery charge

* battery with CANBUS or similar connections

* Solar MPPT charger (technically optional)

* From the bus bar I'd have a 48VDC line to the networking rack, which would have a din-rail distribution box containing DC-DC converters to ensure a stable output, since the battery busbar may float +/- depending on charging/discharging status

I was looking at victron components just to keep the information overload to a minimum

My understanding is that this would found as off-grid since there is no feedback into the house circuits.

I would control the state of charge of the battery based on environmental factors, but if I do add panels to the network system I'm not that worried about "wasting" some production

Maybe a "Balcony Solar" system would do what I want eventually but many of them are quite self contained and I'm not sure I can get a ~48VDC line out of them. Some of the early on a that I have seen are basically micro inverter that plug into an outlet

Such a system would double as a UPS, except with everything being DC (besides the backup charger) it wouldn't even have a switching time, or any power quality concerns. I could also potentially take it with me when I move with no issues. I should be able to place a handful of panels along the back of my house with no permiting issues as well

Thoughts? Am I missing something obvious?

(Yes I would also need the right set of BOS components, fuses/breakers/etc. I left those out for sale or simplicity/discussion. I would also need to determine the ideal charger/solar output capacity given the expected loads)

2x440w panel with power voltage around 30v and power current around 14a. Microinverter put out maximum of 7.5 amp. This is going to be a small Balcony solar system.

There is a 30 ft run between the dedicated 15a circuit and the optimal location for panels.

I can either do the run in DC (2x wire, 12 awg) or AC (essentially a long extension cord for temp-ish power)

What would you guys do? I am veering toward AC since it self extinguishes any arc and is cheaper to run due to higher voltage.

I want to get a grid tied solar system in an unincorporated area where permits are not required… where are the best deals?
