Test the Evolve Hub automatic bypass switch: (start with AK1 relay connected).
1.
Switch Evolve Hub breaker at the main panel to the off position.
2.
Switch the feeder breaker of the backup panel to the off position.
3.
Wait 4 seconds for the Evolve ESS / LFP to transition the PCS into Offgrid mode.
4.
Measure voltages (L1-N, L2-N) at the Load terminals of the Evolve Hub
(~120VAC).
5.
Pull the AK1 terminal (will switch the automatic bypass switch off)
6.
Measure the voltages (L1-N, L2-N) at the Load terminals of the Evolve Hub (0
VAC).
7.
Reconnect the AK1 terminal (after permission to operate (see sec. 5.5)

6 Maintenance
The Evolve Hub is a maintenance free product. Annual inspection is recommended to ensure the enclosure maintains
mechanical integrity (mounting and environmental protection) and the ventilators are free from obstruction. For heavy soiling
use a soft, dry brush to clean. Do not use any solvents, scouring, or corrosive materials to clean the unit. Never remove or
unplug connections or plugs during cleaning.
7 Troubleshooting
The following is a troubleshooting guide for the Evolve Hub. Refer to the Evolve ESS / LFP Installation and Startup manual
for troubleshooting the battery system.
Mode
Condition
Check
Grid connected
No power to Evolve Hub and
backup panel.
Check Evolve Hub breaker circuit at the main panel.
Grid connected
No PV power output
Check PV breaker in the backup panel.
Commissioning / Grid
connected
Battery does not charge
when PV is operating
1.
Check CT configuration. PV measurement is negative when
operating.
2.
Check battery SOC (battery does not charge when full).
3.
EMS operating in solar self-consumption mode, and home loads are
greater than PV.
Grid connected & Backup
Monitoring system not
displaying information in
web portal.
Check internet connection. Check power (Green LED) on EMC panel.
Backup (grid outage)
No power to backup loads
Check status of the Evolve ESS / LFP on the front of the PCS panel. Refer
to the Evolve 0513U Installation & Startup Guide for more details.
