Checking Generic AC coupled
For systems incorporating Generic AC Coupling the following items should be verified. Please note that
“Common System Checks” on page 49 should be completed first.
Refer to document “IN0034_xx SP PRO Generic AC Coupling installation notes” and ensure the system has
been installed and commissioned according to this document before completing the following check list.
•
Turn on the DC supply to the SP PRO(s). Long press the ON button so that only the
blue AC Load LED is lit.
•
Connect SP LINK to the SP PRO inverter(s).
•
Connect the AC supply to the grid feed inverter(s).
•
Turn on the PV supply to the grid feed inverter(s) and let the battery charge from the
grid feed inverter(s) until it reaches the charge target voltage.
Item to check
Result
When voltage goes above battery charge target check that the AC Load
Frequency ramps to 55.2 Hz (No system load, generic inverter is charging)
When the AC load frequency ramps to 55.2Hz, check that the output from
the grid inverters drop to zero and the battery voltage falls.
Check that the AC load frequency drops back to 50Hz when the battery
voltage falls below the charge target.
Checking DC coupled
For systems incorporating DC Coupled renewable energy the following items should be verified. Please
note that “Common System Checks” on page 49 should be completed first.
Refer to relevant document(s) referred to in “DC couple Charge Controller Preparation” on page 34 and
ensure the system has first been installed and commissioned according to these document(s).
•
Turn on the DC supply to the SP PRO. Long press the ON button so that only the blue
AC Load LED is lit.
•
Connect SP LINK to the SP PRO inverter.
•
Disconnect the battery supply to the DC charge controller(s).
Item to check
Result
Record the “Name” for shunt 1 and 2 (Solar, Wind, Hydro)
1
2
Read the Solar (Wind or Hydro) Shunt 1 current in DataVIew - Now tab.
Current should be zero or very close (<0.2 A).
Repeat for shunt 2(if connected) - Record the results
1
2
Connect the renewables and battery to the DC charge controller(s)
Measure the DC charge current(s) with a DC clamp meter and compare this
with the Shunt 1 current.
Repeate for shunt 2 (if connected) Record results.
1
2
Let the battery charge from the renewables until FLOAT charge stage is
reached on the DC charge controller.
Check the Front Panel of the SP PRO to see that its Charging Mode has
dropped to FLOAT..
Put a load on the system until both the SP PRO and the charge controller
drop out of FLOAT.
Turn off the load and let the battery charge back to FLOAT.
Again check that the SP PRO has dropped to FLOAT
