When the Classic is used with Wind or Hydro a Clipper type device will most likely be
needed to protect against over voltage. A battery based diversion load WILL NOT keep
the Classic safe from over voltage. High input voltage is recorded and over voltage is not
covered under warranty.
Never hook a Pump or other load to the Input side of the Classic. If a Load must be
hooked to the input side of the classic the load and Classic need to have blocking diodes
on them.
Never Parallel 2 Classics onto one PV array.
For Larger systems with Large inverters and or multiple inverters (like the Radian or
XW+ for example) it is important to use appropriate sized cables and bus bars or
damage to the inverters or charge controllers can occur. Take a single XW+ E-Panel for
example it has a positive bus bar for Charge controller battery side connections. This
bus bar is sufficient for 2 charge controllers so if you needed 3 or more then you need to
look at the best way to handle the amperage. A Dual Radian for example is actually 4
separate inverters. Proper size cables become very important as well as large enough
battery banks. Most manufacturers of Battery based inverters recommend 100AH of
battery per KW of solar modules. (Please consult the inverter manufacturer for
assistance with cable sizing etc.)
