Got it all wrong....!!!

Got it all wrong! Bought a 48V 5KW Hybrid Inverter, no point in going into detail, I know I bought the wrong thing.

I currently have my system set up in a 10' X 10' wood cabin that I built but will eventually want to move it to a Van build that I am planning and want to avoid Propane, so need good power.

I want to use a Hybrid Inverter. I have attached my Solar panel & Battery specifications which I have 4 of each all connected in Series, panels & batteries.

4 X 190AH 12V Sealed lead Acid Batteries & 4 X 300 Watt Solar panels. (see attached)

I am thinking of a 24V system.

My question is what does anyone recommend what Hybrid Inverter I should be looking at?

Please help,

Many thanks,

Paul

What is the Voc of the panels and max input voltage of the SCC?
This will determine how you wire/configure your array.
This is the specs of the panels:

Specification


Maximum power(Pmax) 300W


Output tolerance ± 3%


Maximum system voltage 700V DC


Open circuit voltage(Voc) 19.2V


Maximum power voltage(Vmp) 16V


Cell efficiency 19.5%


Operating temperature(NOCT) 45±2℃


Temperature range -40℃~+80℃


Number of cells 32pcs


Weight 1730g


Size 1050*540*3 mm


Color Black


Standard Test Conditions : lrradiance 1000w/m²,Temperature 25℃,AM=1.5

These are the Hybrid Models available in the UK, which one to buy?

Did you already buy these panels?
If so where did you buy them from and how much?
Are the so called 300 watt panels flexible?
Suspicious that no max amps are listed coz Amps x Volts = Watts
300 watts divided by 16Vmp is 18.75A!!!!
100 watts divided by 16Vmp is 6.25A

1050*540*3 mm
41.3" x 21.25" so maybe a 100 watt panel.
I would say the 300 watt is highly exaggerated.

This the link for the panels:

Sorry but you got scammed. I was going to ask if you bought them on Wish as this
exaggeration of panel watts seems to be the rule there.
The $2000 marked down to $420 should have been a red flag.
Wish sold you expensive 100 watt panels falsely labeled as 300 watts.
real 300 watt panels are large panels.

Oh well, another costly learning curve, appreciate the response, many thanks.

The positive from the negative is at least I now know I have 400 Watts in total

Never buy panels or inverters or solar stuff on Wish.
Did you buy the controller from Wish too?
I doubt if you could fit 4 large 300w panels on a van.
Dimensions L x W x D1956 x 992 x 50mm
Take Wish.com up on their 30 day return policy.

This fake 300 watt has the amps at 5.55A x 18V = 100 watts so they out themselves as scammers.

Thanks for your input, much appreciated.

No, I did not buy my 48V Hybrid Inverter off Wish thank goodness it is an EasSun and works OK, but I now realize that a 48V system requires more batteries, etc hence my reason for asking my original question to go to a 24V system using my 4 190AH batteries connected in series and parallel & same with my existing solar panels. (had them too long now to return) or do I go 12V?

If I go with 24V then which of these should I buy?
