A300 or A500 Solar Charge Requirements

hello. I have some question about over panelling. I am a bit confused. I have 12 450 watt panels on my roof, on grid system. In the winter they generate about max. 500 to 800 watts. In yhe summer I can get up to around 3000 watts mid day. I am not sure if they are in series or parrallel but I think parallel.

I have ac200max units. I was wondering if I had a power outage in the winter time can I unhook the solar cables going to my inverter and then connect them to the ac200max?

This would be only in case of extreme emergency and hopefully I will never need to do it. Generally I keep my ac200max systems charged using mains with partially supplied solar energy in the daytime. Then I use them at night to power my fridge.

Generally during power interruptions power is restored relatively quickly. Maximum I went was 12 hours a few times. However I am.thinking about this in case of some extreme situation where power may be out for days. My mains inverter does not work when the power is out. I am not even sure what the maximum input voc of the ac200max is as this was something I literally just started thinking about recently.

Really helpful post !

I have an AC300 on order and am following your example… and trying to get some solar panels - they’re a bit scarce at the moment here!

Just a question - I am planning to have 2 arrays:

As I’m sure you’ll gather, what I’m trying to ascertain is: can I fiddle around with the set up until I find the array sizes and locations that work best for me ?

Presume I’ll need a pair of parallel connectors like the Rich Solar ones the other guy needed … ?

Think that’s about it for now.

Thanks

Next day… this is my latest proposed configuration:

I see it’s a good idea to add FUSES to the panels connected in parallel… each panel has a Short Circuit Current of 10.72 A so I presume I’ll need 8 for 2 arrays of 4 panels in parrallel plus 2 more for the combined arrays entering DC1 and DC2 … ?

AI (lol) is suggesting I use 20A fuse for each panel in parallel (8 in total) and then get a 60A DC Circuit Breaker for each of the combined arrays.

BTW I’m in the Philippines.

It all sounds good to me :) , but as you’ve probably gathered, up until yesterday I knew absolutely nothing about Solar Panels!

So really appreciate your feedback on this - thanks.
