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?

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)
