E.M.P Systems Only
Suppressor installation
• If your system was purchased with Lightning / EMP Hardening, the vast majority of protection is in the Sol-Ark.
However, you also have EMP suppressors that get installed on the power cords of appliances that are connected to the
transfer switch. Although not critical, it is recommended they be installed as close as possible to the appliance.
• You also have EMP suppressors that get installed on both solar panel wires with a zip tie. Closer to the panel is better.
If you purchased the panels from us, we already installed >150kV/m protection inside the solar panels.
Connecting Solar Panels
A. Sol-Ark has DUAL MPPTs for two separate PV input pairs
B. MAX PV input = 13kW (± 5%) / system | 6.5kW / MPPT | MAX 500V
OC
PV | MAX I
SC
/MPPT 25A (limiting to 20A)
Damage will occur if PV V
OC
> 550V
C. Parallel strings per MPPT must be the same Voltage
i. PV1 A/B must be the same voltage if using both strings
ii. Panels on the same MPPT CAN face different directions
D. Ground the panel MOUNTS/FRAMES to any ground in the Home via 12AWG wire
E. IF using Y-Connectors: Running two strings in parallel, totaling 20A (self-limiting)
F. Connect the solar panel strings as indicated by the following diagram:
Each string can use separate
wires
String minimum is usually 5
panels or 175V
