Hi,
I've been trying to find a solution to my problem of being limited to small series panel strings due to shade issues. So I have lots of small arrays dotted around my garden. To be precise I now have arranged them so that I have 6 strings of 3x175w in series. The output is around VOC 63 and Amps 9ish for each string.
I tried putting them all into a 6 into 1 mc4 combiner but the AMPs is then very high and at certain parts of the day I'm losing out on lots of solar energy.
Is the some device I can plug them all into and then step up the volts and step down the amps before feeding to my mttp controller ?
I guess some device where you program in say max amps 15 and it then takes the energy as it comes in a bumps up the volts as required to stay under 15 or at 15 amps?
I found some very small things called buck booster but they only handle tiny energy like 5amps.
How can I solve this issue? Or is there an mttp controller that can take maybe 60 or 100amps solar Pv input?
I was told generally mttp contollers are designed to step down V to A not the other way around.
Would be great to find some device where I can plug in all my solar energy and dial down the amps to a level that my mttp can optimally use.
Does such a device exist for larger than 5amps or 90v? Is there a name for it other than step up or buck booster? I saw a digital step up booster which you could set but it needed stable input to convert which with solar pv input is impossible.
I think I need something like an mttp which is made to step up volts and step down amps? Then send that to my bluetti or new growatt or mpp solar set up. It's a shame their input pv amps are set lower than 80-100amps. I could add more solar arrays in other spots but the combined amps is growing out of control.
Thanks for any ideas how to solve this.
