[RE-wrenches] Paralleling CC

[Jay]

Hi All,

Are there any CC out there that can parallel on the input side?

Situation is a older 12v system, 300’ wire run using a MX 60. 

Client wants more PV, but CC is maxed out. Upgrading to say FM-100 is way expensive and needs new mate etc. 
Yes could totally redo the system to 24 or 48v and use iota for 12v loads. Buts that’s  expensive. 

Installing new wire would be complicated and expensive. But wire is large enough to handle more power. 

Are there are any cc that can parallel on the input side, which would be the easy solution if it exists 

Thx

Jay
