I recently found out could end up with a over voltage situation  with my make Sky Blue charge controllers (ty sid)

Even though 3 series connected panels don't go over the maximum 150 volts

Solar panels and sometimes do over the maximum voltage

It would be nice to have Sean Buckner to put a list of his recommendations on here input volts amps output volts amps 

It would also be nice to know if there was any hacks i could do to raise the input voltage 

If the caps was the only problem those are easy enough to up grade

Even the mosfet wouldn't be to hard 

Has anyone tinkered with these charge controllers??

Rated Output

 

The maximum PV input power. The total power rating of PVs can’t be over this Wattage.

 

 

 

 

Voc from PV

 Voc is 1.5 or 2 times the battery Voltage for it’s best efficiency. )

Thanks water man I was thinking the caps inside and top voltage of msb is 150 volts 

I will have to open one up and check components again

The two at the output on mine are 100V. The rest are rated 160V. So when they say 150 Volts, better stay at that or lower.
