Do i need solar?

[Dellmassive]

Thanks. That sounds a bit "once started - no going back" lots of problems.

So from the top surface of the pop top to the bottom of the void underneath it, I would need about 40mm.
Will have to see what I can work out at the weekend.

That will depend on you're panel...

Mine was around 35mm from the underside of the panel to the bottom of the rear gland with the radius of the cable.

Just look at all this lovely free* energy you'll be missing out on with no solar...

95w and it's not even 9:30 yet!


*Not including the cost of the panel, MPPT, wiring, installation costs, bribes to the other half

Hi Guys,

Can Victron Energy BlueSolar MPPT 75V 15A charge controller work with the Renogy 200W Portable Solar Panel (https://www.amazon.co.uk/Renogy-Portable-Waterproof-Foldable-Charger/dp/B0CNPHD4VY/ref=pd_ci_mcx_mh_mcx_views_0_title?pd_rd_w=rpwZt&content-id=amzn1.sym.d63274d0-bf52-45e7-ae69-2bcf85c5865c:amzn1.symc.ca948091-a64d-450e-86d7-c161ca33337b&pf_rd_p=d63274d0-bf52-45e7-ae69-2bcf85c5865c&pf_rd_r=RT71SYA7TSD4SKGWS1YA&pd_rd_wg=pDqHx&pd_rd_r=a4e729e7-fd3a-435d-bace-bea9c387684e&pd_rd_i=B0CNPHD4VY&th=1)

Thinking of an upgrade from Lensun 100w Potable SP to Renogy 200W, and I already got Victron 75v 15a MPPT

Do you have the BlueSolar or the SmartSolar? Rather confusingly the "BlueSolar" one is the one without Bluetooth...

For solar you need to look at what total Watts the MPPT can handle and the maximum voltage - the Open Circuit Voltage.

So that listing has 200 watts and 23.40 volts.

Looking at the SmartSolar MPPT 75/15:



So you are comfortably under the 75 volt limit, but quite close to the 220 watt limit - given most panels never reach the rated output in real world conditions you're probably fine

The max wattage doesn't actually matter, so long as the other parameters are met. You can use a bigger wattage panel, it just means you'll get to the max amps output sooner and get more solar power at all times except for when the panel is maxing out - which lets face it, is almost never!
