Sungrow SH3K6 - Inverter Mounting Procedure

User Manual 3 Function Description
25
The maintenance process is as follows.
1. Charge the battery with a constant current according to a C-rate of 0.165
C. C is the nominal capacity specified by the manufacturer and is
indicated in Ah.
2. Charge the battery with a trickle current when the battery voltage is
stabilized at the average charge voltage.
3. When the trickle current decreases to 3 A, end the maintenance.
3.3.4 Battery Temperature Sensor (PT1000)
The inverter has integrated a PT1000 temperature sampling port for lead-acid
batteries. With the external PT1000 installed, inverter can sample the
temperatures of the external environment or the battery cabinet. The system
uses the sensor input to perform power derating, battery over-temperature and
under-temperature protection.
The sampling temperature of PT1000 ranges from -25°C to +60°C, with the
accuracy of ±2°C. The protective temperature of lead-acid battery ranges from
-25°C to +60°C and the values could be set on the LCD or the iSolarCloud App
or the iSolarCloud server.
The temperature sampling function of the sensor PT1000 for lead-acid batteries
is disabled by default. Refer to “10.4.12 PT1000 Switch Setting” to enable the
function via LCD menu.
