ATTENTION: Please Read this cover letter BEFORE installing the Classic

For help with the Classic, Classic Lite or Classic-SL please see our how to videos and extended documentation. Please visit this website: www.midnitesolar.com/classic Before calling tech support, we recommend visiting this website for some of the most common issues.

Warning: Arc Fault protection is not turned on by default. (Note neither the Classic Lite or Classic-SL haveArcFault built in) The National Electrical Code article 690.11 requires Arc Fault Protection. The Classic has this built in as standard equipment. This will need to be enabled if so desired.

Please Note: The Arc Fault Protection has adjustable sensitivity and may require some tuning for your particular system to avoid nuisance tripping. Some house loads like Table saws and well pumps and other motor loads can actually be seen on the PV circuit in the Classic appearing similar to DC arcs. We have started with a general average we have found to work reliably but in some cases this sensitivity level is too high causing false Arc Fault Alarms. When the Classic goes into Arc Fault, it goes to Resting and will not charge the batteries. Please consult the manual that came with your Classic for enabling and or fine tuning of the Arc Fault system.

DANGER OF DEATH TO YOUR CLASSIC

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. If 2 Classics have to be paralleled for wind or hydro (NOT SOLAR) there must be blocking diodes on each Classic.

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.)

IMPORTANT!Do not mount in a zero clearance compartment. Overheating may result. The Classic produces heat in normal operation. Airflow around the Classic is required to prevent overheating andshutdown. This is especially true in hotenvironments.

Uploading New Firmware to the Classic

WARNING! The Classic's USB port is NOT isolated from battery negative. This is typically only an issue on positive ground systems or systems with a tripped ground fault protection device. Care must be taken that a computer connected to the Classic's USB port is either isolated from ground and the Classic's negative or that the computer's USB negative is common with the Classic's negative and ground.

WARNING! You cannot turn a Classic 150 into a Classic 200 for example using new software, the internal components are also different.
