DC voltage in the system meaning that non-compliance with the maximum permitted
limits can be checked.
- Note the temperature coefficients in the solar module data sheet
- More exact data for sizing the solar modules for the particular location can be obtained
using calculation tools such as the Fronius Solar.configurator (available at https://
www.solarweb.com).
- See NEC table 690.7 for the appropriate voltage adjustment factor for crystalline sili-
con solar modules, or use the manufacturer’s specified voltage coefficients.
Connecting Alu-
minum Cables
The DC-side terminals are designed for connecting single-wire, round aluminum cables.
Due to the reaction of aluminum with air that creates a tough, non-conductive oxide layer
the following points must be considered when connecting aluminum cables:
- Reduced rated currents for aluminum cables
- The connection requirements listed below
Connection Requirements:
Carefully clean off the oxide layer of the stripped end of the cable, e.g. using a knife.
IMPORTANT! Do not use brushes, files, or sandpaper; aluminum particles may get stuck
and can transfer to other cables.
After removing the oxide layer of the cable end, rub in a neutral grease, e.g., acid-free
and alkali-free Vaseline.
Then immediately connect it to the terminal.
Connecting Solar
Module Strings to
the Inverter
NOTE! Before connecting solar modules, make sure that the voltage specified by
the manufacturer corresponds to the actual measured voltage.
Note the safety instructions and specifications of the solar module manufacturer
regarding solar module grounding.
NOTE! Always follow the instructions of the cable manufacturer when using alu-
minum cables.
NOTE! Take into account local specifications when configuring cable cross sec-
tions.
IMPORTANT! Repeat the steps above whenever the cable is disconnected and then re-
connected.

CAUTION! Risk of possible damage to the inverter! Check the polarity and volt-
age of the solar module strings: the voltage must not exceed the following values:
Symo Advanced 10.0-3 - 12.0-3 208–240
- 0–11154 ft (0–3400 m) = 600 V
Symo Advanced 15.0-3–24.0-3 480
- 0–6561 ft (0–2000 m) = 1000 V
- 6531–8202 ft (2000–2500 m) = 950 V
- 8202–9842 ft (2500-3000 m) = 900 V
- 9842–11,154 ft (3000–3400 m) = 850 V
IMPORTANT! You should only remove the number of knockouts required for the available
cables.
