Sorry you've confused me.
The wanderer is 30a to charge 12v system (360w) it will also accept up to a max input 400w from the solar panel which in my case will be a 320w.

So from what I've learnt so far mixing the panels in a series will simply add the voltages together but keep the Amps at the lowest rate. So I've got a 150w panel at 18v and 8.43a, a 320w panel at 32v and 10a, im going to be adding up the 32 and 18 which is 50v, and the total amps current would...
Hi
Thanks for responding
I'm still a little confused
So the mppt controller instructions says it's mppt pwm mode.
I agree it will only charge what the battery can go at that makes sense, but what does it do with the excess volts? Is this why there is load on the controller?
The charge...
Yes it makes sense, what doesn't make sense is these 30amp controllers that say 30a for 12v/24v but don't say what input the panel volts it can handle.
Just to confirm I could run this mppt and my current cheap Contoller on the same battery?
Thanks
Lee
That's great advice thanks both.
I'm now questioning if it's a pwm controller because it was only about 10 pounds from China lol. Will that be an issue with the volts? I've attached the tech sheet.
I would be willing to upgrade my battery to 24v system if needed.
I want to get the most out of...
Thanks.
If I wanted to make the most out of the 160w panel on the current controller I was thinking if I made my existing 12v a 24v battery circuit then the controller can accept between 36v and 48v but im assuming the 160w panel wouldn't be able to produce that and it won't work because its...
Thanks
The seller has offered to test and diagnose for free, I just need to pay shipping.
I might try this first, but I hope it's an easy fix like you are suggesting. I wish I could solder.
Thanks

Hi
I have 1 x 160w solar panel which is about nearly 9 amps max, the max voltage must be about 18v.
Its connected to a 20amp MPPT and PWM charge controller with a 12v 120ah leisure battery.
The power rating of the cables from the charge controller to the battery are 10 AWG which carry up to...
Hi Chrisski
Thanks for the reply.
I did the maths
If you work it out it would go off the lower amp in series so i would lose an amp.
160w / 9 = 17.7v
320w /9 = 35.55v
Total = 53.2v x 9amps = 337.66watts
I'll buy a seperate charge controller lol your right
So to make the most of the 160w...
That sounds good.
I just need to make sure I get the correct mppt then? I think what I have is an mppt but im not sure of the difference. If i bought a pwm by accident would this still work as a 2nd one? Whats Scc stand for? Solar charge controller?
So to make the most of the 160w panel...
I can only see 30a charge controllers that do 12v or 24v and from the spec it says like 380w for a 30a at 12v. So i think it converts it down like an mppt especially when you can edit the volts on the unit.
Yeah I did see them but the cheap Chinese one has been great on my 160w panel.
If I bought this could I tie it into my electric? If im spending 100 on a mppt should i not consider a tie in grid and battery charger...
Thanks
Only thing that confuses me is that the charge controller will only charge the battery at 14v, its a 20 amp mppt but if the solar panel max amps is lets say 9 amp then it isn't going to produce more than 14v x 9 amps = 126 watts out of the 160w panel.
If the panel is 9 amps and your...
Hi guys
I have a 1.2kw hybrid off grid inverter.
Around 6 month's ago it kept making a high frequency noise and then went away.
In October I went to turn on the inverter and it was dead.
The battery is 100%, the solar input is fine. I tried connecting 240v power to the input on the 240v...
Thanks JWLV
The current controller I have allows me to set the volts for charging.
I'm assuming for that 320w panel I'll need a 30amp controller? I'm also assuming using a 30 amp charge controller that supports a 12v battery means it will work at 10.6v? or could I use a 20 amp controller as...
watching that video I have come to the conclusion that the PWM wanderer is the best and cheapest as it doesn't do anything different from the MPPT even in cloudy conditions. Only thing to be mindful of is the temp sensor as its a lead battery im using.
Hi guys I'm really sorry, I didn't get a notification that anyone had responded.
Unfortunately the unit is no longer under warranty and the company want £70 before even fixing it.
The unit is a conversol mpp solar hybrid 1.2kw.12v system with dual mppt inverter.
Visually I cannot see any...
Hi guys
Hi
I want to use my solar with a tie grid inverter and if possible run it with my current off grid, but dont think thats possible.
I have been doing my research and using my 150w and 320w solar panels in a series I will have a total maximum circuit voltage of 62.9v.
The spec of the...
