Looking at a lot of the MPPT controllers and the majority of them seem to be limited to handling a maximum of 150Voc which makes for larger cabling and a lower series panel connection arrangement.
At the moment I have my panels setup as 4 in series with Voc of around 38V so the Voc ands up around 152V (higher in cold weather !) and would ideallk like to have 5 and 6 panels in series to better use the space on the roof, but struggling to find a charge controller that makes economic sense.
Grid tie inverters go upto 680V for domestic size and can track down to use 5 panels in series but I am looking for a 48V charge controller and so far I can't find one that fits....
Anyone know of a 48V charge controller that takes >150V open circuit and does not cost a fortune... ?
