Photonics Panels And Ablemail

[Martin Gibson]

Hello,been looking at the above panels in 250w,the same as @Deaky 's one and there is a 300w one now that only £30 dearer. I was wondering if @travelvolts or anyone else could tell me if the Ablemail 12-12-30 can take either of these panels,thanks very much

Post a link to the panel you were interested in.

Search @Deaky panel post for help, sure his is 350W.
Simply the panel will spec the max O/P voltage - Look at the Photonics site for details. There's also an Ablemail site which provides max voltage each unit can handle.
I've used a 250W Photonics / Ablemail combo and it's fab.
Otherwise contact Martyn @travelvolts for help

That will be.


Solar panel specifications:

• Peak power: 300W
• Maximum power voltage: 37.3V
• Maximum power current: 8.1A
• Open circuit voltage: 45.5V
• Short circuit current: 8.6A
• Dimensions: 2020 x 991 x 2 mm
• Weight: 5.5 kg

So:

• Open circuit voltage: 45.5V
• Short circuit current: 8.6A

Let's see what the ablemail can handle.

 

[Martin Gibson]

Oh @Wills ,you actually have that actual combination? Thats great to know,thanks very much,be nice if the Ablemail could handle the 300w for an extra £30 but i will be happy enough with the 250w if not,thanks again

It looks like 32v max solar and 30amp max through put for that ablemail.

 

[Dellmassive]

It looks like the 45.4v OCV of the panel is to high for the Ablemail solar input.

 

[Martin Gibson]

Oh well, the 300w in the second link is no good then but the 250w in the first link should be ok?

 

[t0mb0]

The open circuit voltage of that 250w panel is greater than the 32v on the ablemail spec.

I have that same 250w panel and I actually spoke to the ablemail designer who said it wouldn’t handle the panel.

 

[Dellmassive]

250w first panel.

Solar panel specifications:

• Peak power: 250W
• Maximum power voltage: 31.17V
• Maximum power current: 8.02A
• Open circuit voltage: 37.57V
• Short circuit current: 8.41A
• Dimensions: 1657 x 991 x 2 mm
• Weight: 4.5 kg

So:

• Open circuit voltage: 37.57V
• Short circuit current: 8.41A

That's a bust then as it exceeds the 32v solar input.

 

[Dellmassive]

Why not get 2x smaller panels, that will work.


I've gone for 2x 150w panels, 300w total.

In parallel the voltage stays the same as one panel but the current doubles. So you can use that solar controller.

 

[Martin Gibson]

Oh ok,i thought @Wills was saying thats exactly what he had? Which charger do you use with that panel then @t0mb0 ?

 

[Martin Gibson]

Thats what i might have to do Dellmassive,i really like the Ablemail but fancied the ease of one panel over two but if its no good then your way sounds good

 

[andys]

You could have the 300W if you use a Victron controller

 

[Dellmassive]

You could have the 300W if you use a Victron controller

LOL, was just gonna suggest that,

Oh ok,i thought @Wills was saying thats exactly what he had? Which charger do you use with that panel then @t0mb0 ?

I have a Votronic MPP 250 Duo.

 

[Dellmassive]

I've just started a survey for members:

What Solar Panel & Controller ?

 

[Martin Gibson]

Thanks for all the advice,plenty of options then,seperate controller and bigger panel or all in one charger and 2 smaller panels,plenty to think about

take a quick look at this explanation re parallel vs series :
