2. After the SP PRO has powered up and the front panel LEDs are stable, check the green LEDs on

the blue comm card.

Note: During the SP PRO power up, the front panel display cycles through three stages. First, all

LEDs turn green from bottom up, second, all LEDs turn red from bottom up and third, some LED’s will be flashing while the battery LEDs are ON solid green. The third stage is what is referred to as stable.

The right LED should be steadily ON.

The left LED should flash approximately once per second.

NOTE: There may be a delay of up to 60 seconds after power on before the left LED

starts flashing.

3. Navigate to “Data view > Battery Management”. If the system is working correctly, the values on

this screen will be valid for the batteries.

4. The Module Status readings are greyed out as they are not used with the batteries.

5. The values displayed under Battery Management are those read from the batteries.

The SP PRO uses these values to adjust the charge current and to limit the discharge current in

the battery.

Note: The SP PRO will be beeping and

the batteries will turn off after 5-10

minutes if there is a problem with the

communications between the SP PRO and

the batteries.

Operation of the SP PRO

The SP PRO reads all the data out of the batteries and automatically adjusts the battery current to suit.

This means the operation is a little different than with other battery banks.

When connected to the grid, the operation of the SP PRO is as follows:

1. When the SP PRO is charging the charge current will be limited to the “Charge Current Limit” as

displayed in Battery Management (see diagram above) and the charge voltage limited to “Charge

Voltage Limit”.

2. When the SP PRO is supporting the load, the current taken from the battery bank will not exceed

the “Discharge Current Limit”. The SP PRO will adjust its maximum support power to ensure the

discharge current is not exceeded.

When the grid fails, the operation of the SP PRO in standalone mode is:

1. When the SP PRO is charging from the PV, the charge current will be limited to the “Charge

Current Limit” as displayed in Battery Management (see diagram above) and the charge voltage

limited to “Charge Voltage Limit”.

2. When the SP PRO is supporting the load, but the current drawn from the battery exceeds the

“Discharge Current Limit”, the SP PRO will go into current limit and reduce its output voltage. If

the load so high that the AC voltage drops below 200V for 10 seconds, the SP PRO will shut

down as the battery can no longer support the load. The customer then needs to reduce the load

so that when the SP PRO retries, it can continue to provide backup power.
