I have just installed a Victron Easysolar 24/3000/70
The PV connections x 2 sets of CF4 under the inverter are tricky. Please let me know how do I know which are positive+?
In trying to connect a second array I have got the poles wrong, so have now have an error of over current #37.
Victron says the MPTT is protected. Is there a fuse I can replace or do I need a Technician to reset the MPTT?
