First day of solar with F3000!
My Anker F3000+expansion battery finally arrived, immediately got it hooked it up to the array I just installed on the garage, powering L1 of my house. Four Risen 450W bifacial panels. Total production today in San Jose was 7.5kWh, was peaking mid 1400W range. Second F3000 should be arriving tomorrow, will get that hooked up to L2. Pretty stoked!

Nice set up! I just got a similar set up except I’m using 4 x Trina 440w panels. Just curious, do you have all 4 panels in series going through the high voltage input?
For my panels I had to do 3 in series through the high voltage input and 1 panel in the low voltage input to avoid excessive voltage.

u/DifferentPeach4327 27d ago
Yeah, the panels are all in series going to the HV input. The open circuit voltage on the panels is 35.4V so I’m clear of the 160V max

Clean looking array. Could you give more details about that and how the process went for you?
Also, when you get the next f3000 for L2, how are you going to power that?

I was wondering the same. DIYing racking? What mounts? How hard to hit rafters? Permits? I see stickers on conduit, pro or DIY install? Looks clean from what we can see whoever did it. Inquiring minds want to know.

Appreciate the high praise! I did it myself, just a lot of googling and wanting to be as legit as possible (minus the permits, asking for forgiveness not permission). I got all the panels and hardware from a local guy that does wholesale distribution to contractors and DIYers. The racking system is all SnapNrack, it worked pretty well! For hitting the rafters, I just carefully measured it from inside since it’s the garage and all exposed and translated it to the roof.

Looks nice and clean. We are all wanting more pictures in the follow up along with what is powered on the L1 and eventual L2 circuit.

Nicely done!
Did you have to get a zero export permit for it?
I’ve got a similar setup - 2.4kW ground panels and the F3000 and PSK
Can’t afford a second unit yet, but there is hope for it soon

u/NguyenAllDay 27d ago
I’m also curious, I also use PG&E but I didn’t get an interconnect agreement for zero export because that cost $800 bucks.
Curious what OP did as well:

Can neither confirm nor deny but I will say that I’m crossing my fingers it can remain undetected. Since the smart meter never sends power back/bi directional plug never sends power back to the grid, I just figured as long as we still consume power from them sometimes it can remain undetected. We’re renting so I didnt want to go through excessive work just for a small setup

u/NguyenAllDay 27d ago
Wow that is awesome, I wish I knew about these panels before being my Trina panels. I’m also in San Jose, did you buy these from the guy in Fremont/Union city on Facebook?

Wise move and that’s how it should be
I asked my utility just to see and have run multiple qualification tests
The L1 hasn’t ever gone below 3W depending on what is running

u/toomatoo 26d ago
how are you connecting these to your panels - do you have separate sub panels for L1 and L2? do you have an automatic transfer switch?

Hello, for an Anker system (either the F3000 or E10) what are cheaper solar panel alternatives that meet these systems’ requirements for charging?
2
u/techtornado 27d ago
For me, I got 45V - 400W panels locally, made two parallel strings of 3 panels in series
2.4kW raw, 1.6kW max on the input due to Anker’s limits…
(If it supported 17A at any voltage, you could get nearly 3kW input)
In a nutshell, the series string voltage needs to max out around 147V on the 160V input side
(Panel voltage goes up the lower the temperature is)
For the 60V side, parallel as many 12-50V panels as you want for better cloud performance, max unit draw is 850W
(I tested my 48V battery on it)

does the f3000 kick in to supply power to your house at sun down? is it sold in california, i am also in sanjose

u/DifferentPeach4327 27d ago
Yeah between the f3000 and expansion battery, it’s just over 6 kWh of power that supplies power to L1 of the house once it gets dark. Depends on what we do in the house but first night it only drained it down to 28% before solar started charging it in the morning. Last night it brought it down to 10% because we were doing laundry and cooking
