How to analyze issue about SPH 3-6K OR SPH 3-6K UP based on history data

How to analyze issue about SPH 3-6K OR SPH 3-6K UP based on history data
1. Dashboard
2. Test server

35 server:

2. history data analysis


1) Status:





Battery online

PV Bat Online…

PV Bat offline,

Battery offline



2) inner_version:

Firmware version:
Letter is corresponding model,Number is corresponding different chip
Standard SPA:YHAAxxxxxx
Standard SPH:YAAAxxxxxx

3) SOC:


On EPS mode, battery capacity has at least 20%, until 95%, it won’t be charged again

3) “AC Charging power:INV side imported power from grid”
4) AC Power:INV Exporting power
5) Vac1, EpsVac1

Vac1 means utility voltage

EpsVac1 means EPS output voltage, for SPH 3-6K UP, if inverter switch from EPS to utility, on EpsVac Column ,it will display utiltiy voltage like above.

6) AC Power:INV Exporting power

The power imported from the grid: The meter upload the data

7) Exporting Power:Exporting power to grid
8) Local load power

PlocalLoadR = Ppv+Pbat+Pmeter1+Pmeter2

9) Priority

0: Load First: PV and battery will supply for load as first priority, when PV energy is greater than load power, secondary priority is battery, , Third priority is Grid

1: Battery First: PV and Grid will supply power for battery system as first priority, battery charging percentage can be set;

2: Grid FirstPV and battery will supply power for inverter output as first priority Note that this is the output end of SPH, regardless of load and grid, the battery discharge percentage can be set;

Note: when inverter is on off grid application, you can’t set load first, or it will alarm 401 warning. On EPS mode, priority funciton won’t work

10) Bus Voltage( INV side Sampling Bus voltage )
11) Bus Voltage( DC side Sampling Bus voltage )
12) Temp1, temp2, Temp3

Temp1: NTC Sampling:INV Radiator Temperature

Temp2: NTC Sampling:Boost Radiator Temperature

Temp3: NTC Sampling:BDC Radiator Temperature

13) SysFaultWord1, SysFaultWord2, SysFaultWord3, SysFaultWord4
14) BatteryType

0: Lead acid battery

1: Lithium-ion battery

15) UwSysWorkMode

Standby: 0

Checking: 1

Fault: 3

Programming: 4

PV Bat Online: 5

Battery online: 6

PV Bat Offline: 7

Battery Offline: 8

Bypass: 9

16) BmsGaugeRM(AH)

Battery Remaining Capacity: The value should shrink 10times.

17) BmsGaugeFCC(AH)

Battery Max Capacity

18) BmsDeltaVolt(mV)

BMS Cell Voltage difference
