WANTED - Cheap PWM Controller and Leisure battery

RAW

Full Member
I am selling Sylvia, decision 95% made, and I want to take the decent AGM and Victron Kit out.
If anyone has any unwanted PWM controller and a Leisure battery, 90AH up, going spare then that would be great.
Controller needs to handle 285W panel below:

Thanks in advance

I know you want to have a controller in place for the panel for sales purpose, but with that voltage output, a PWM will perform fairly badly compared to an MPPT.
Having said that, if you need one that will cope with the specs, I have one you can have for cheap. From memory it is 20A, 60V, 400W unit and has a temperature probe and a display. (For a PWM controller it is remarkably well specified!).

Sounds fine to me, the Victron MPPT is 30amp, bit over Spec but if and when I get a new Van then I want to look to get over 1KW of Solar on the roof and also use the Tilt type that @StreetSleeper showed me on his van.
Bang me an email with what you want for it and will send you some ££

Cheers
Robert

Just had a look at the specs of the controllers I have knocking around ...
SC - Test Controllers by David, on Flickr

The three on the right are PWM - from top to bottom, they are 30A, 20A and 10A.
The 30A is a flush mount unit and would involve reworking cabinets to fit, so forget that.
the 10A unit is like the most common cheap unit you see for sale, and it is ok on current and also on voltage, but they only manage upto 130W, so forget that as well,
So like Goldilocks and the three bears, the one in the middle is the best fit - 20A Max Current, 55V Max Voltage and upto 340W Input Power
It is this unit here from Poyang Solar (which is my direct supplier in PRC) - http://www.puyangsolar.com/product-40.html

Wouldn't leaving the goodies in, get you a better price? I'm still improving Murky even though it's doomed to be sold.
My son said the same but I doubt if leaving Victron Units and a good AGM Leisure Battery will improve the sale price by as much as I paid for all the kit, from memory about £400. I want to keep the VIctron Kit and might sell the MPPT controller on EBay I have and then reinvest in a BT enabled Victron MPPT. Keep me posted on Murky as it could be the Van I am after though would like one sooner than you plan to sell.

Most people don't understand how much decent kit cost and would be reluctant to pay close to what it is worth, so I think Robert is on the right track.
That is why the super-basic Bull Banner batteries are so popular when better ones are available but at a higher price. Same goes for the Victron MPPT.

If I built myself a new Camper, just about all the electrics stuff in Clarence would get transferred over.

The danger is, unless the vehicle is fully functional with no holes to show where something once was that could devalue it too. I guess your installation Dave is above and beyond normal.
