Dealer Information Screen
For dealers‘ convenience the Classic has a display screen that can be modified to publicize the dealers‘
business information. This is helpful because the customer will know who to contact in case they want to
report any problems regarding the product. This will also help to promote retailers‘ accessories that are
compatible with the Classic. This screen is capable of 20 characters per row and four rows, for a total of
80 modifiable characters.
To modify this display screen, follow these steps:
 Press main menu
 Scroll to MISC and select it
 On the following screen, select MNGP and press enter
 On this screen select LOAD DEFAULTS press enter
 On the password select 365 and press enter
 Using the up and down keys will allow you to change the alphabet characters
 Now scroll left and right to go to the next character block
 Do this until your desired message is complete
 Press enter to save on the classic memory
Positive Ground systems
When installing the Classic in a positive ground systems there are a few extra steps that need to be taken.
The Ground fault jumper needs to be removed, and ground fault needs to be disabled in the menu. Refer
to page 19 for instructions on doing this.
The overcurrent protection needs to be done a little different as well. The input and output breakers need
to be double poles. Battery negative and positive conductor both need to be protected. Refer to Classic
Breaker Sizing. Table 6.1
IMPORTANT: Do not connect both, positive battery and positive PV input to ground. One or the
other positive (normally battery +) but not both otherwise the Classic input and output will be
shorted.
HyperVOC ™
HyperVOC is a unique feature the Classic has built in. HyperVOC refers to; when the DC Input Voltage
raises above the maximum operating voltage (150V, 200V, 250V, depending on the Classic model).
HyperVOC gives you the flexibility to go up to the maximum operating voltage PLUS the nominal
battery voltage. For example, the Classic 150 has an input voltage rating of 150 operating volts, if the
Classic 150 is connected to a 48 volt battery bank, the HyperVOC voltage limit will be: 150V + 48V a
total of 198 Volts that the Classic can withstand without breaking. When the Classic input voltage rises
above 150 volts it will switch off (stop outputting power). As long as the Classic is in HyperVOC mode,
the microprocessor and all other functions like AUX will continue running. When the input voltage comes
back down below 150v (or the rated operating voltage of the Classic, depending on model) the Classic
will wake up and start charging again automatically. This could happen in a really cold morning with a
system that has a Voltage Open Circuit (VOC) close to the maximum operating input voltage.
Note 1. A HyperVOC message will be displayed on the bottom right side of the Status screen.
Note 2. Max nominal battery voltage to be added is 48v
