We have a AC200 Max and need a longer cable to run from camper to solar panels.
Does anyone have a recommendation on best place to buy them ?

Hi @jaxstraw
i buy my MC4 cables from ebay. Never had any issues yet. I can give you some links but its a german ebay shop. Dont think they ship in the US or anything that much more far away that germany

Amazon has a variety. Search for “MC4 extension cables”. I would suggest running the voltage as high as possible without exceeding the input limit for best results.

Typically you can buy 4mm^2 for distances under 50m - and upgrade to 6mm^2 for distances between 50 and 150m.
Ebay is a good option as @Selfmadestrom mentions. Or buying the crimpers and cable to install the connectors yourself is much more cost efficient than buying them pre-made on amazon.
All depends on your needs. One shot, go for ebay 
Shouldnt we advise to stay at least 10% below the unit’s Voc?
That would be safer if your are close to the limit.
