Rigid Solar panels for AC500

What rigid solar panels can I buy if I wanted to max out the solar charging input? Like what model and how many units. What type of connection configuration with this method use?

It’s 150V max
This is the only spec you have to watch out for.

A Panel like this:

has 435W version 51.8VOC so 3 would give you 155,4V I would risk it by going 5,4V over speck!
Under load the voltage will drop to 130V anyways.

with best case giving you 10A so you would get a maximum of 1300W. but more realistically with some losses maybe halve that.

if you want to play it super ultra save you can only use 2 in series limiting you to ~85V under load
with the maximum charging current of 15A this would limit you to 1300W no matter how many you put in parallel.

So i would put 2 in parallel and 3 in series. this shuld give you ~2000W.

Thanks. How can I bump it to 3000w. Which I believe is the max and would charge faster?

In the manual it says it can max. 15A and 150V so taht’s 2250W not 3000W

But you can also Charge it from 24V DC wit 8.5A this would give you another 200W
(but you would need to buy a 24V solar system as well)
With another 2500Wh 25V battery and charge controller this would cost you ~600€
and you could add ~4 more panels.

EDIT:
So the manual says it has 2 Solar inputs.
So you can make 2 stings of 3 solar panels in series 2 Parallel.

This would give you the full 3000W of charging if you have ideal Sun and cold weather.

You would need in total 12 of this “420W” Class roof top panels costing around 100€ each

if you also uses BLUETTI B300 or better BLUETTI B300S you can add solar panels to them as well.

I only see one solar input. it does say DC1/DC2 so I don’t understand that part. Do I need to buy an adapter that splits into two?

Is the Adapter (and a manual) not included?

The AC500 has two inputs: DC1 and DC2. Each can produce up to 1500W totaling 3000W. You just need to make sure you do not exceed 150Voc for each of these (DC1 and DC2)

I am considering the Renogy RSP550D-144. Each Panel is rated with a Max Power of 550W, 49.95Voc, and short cirucuti current 14.05A. 3 of these wired in series would produce a maximum of 1500W in the AC500 under perfect conditions. Two sets of 3 would be 3000W. I’m also considering the 450W version of this panel.

Why?
Don’t seam to be a “name brand”

They don’t even seam to be a manufacture but only a reseller

So you don’t really know what you get and they are not even cheap?!

In Germany i pay 20-25cent per kWp of name brand cells.
this Panels are like 4 times more expansive?!

If you don’t have a good reason to do so i would go with the biggest panles since Mounting hardware is a significant part of the cost and you need less mounting hardware per kWp with bigger panels
