As an example, I will set up an SRNE HSI 3000S inverter with a Lifepo4 battery and describe the parameters that I set up.
00 ESC (exit menu)
01 Uti (Utility – power from the grid is a priority, switching to the inverter if there is no grid. SOL – power from solar panels (PV) is a priority, switching to the grid if PV is not effective or the battery voltage is below the value in parameter 4. SBU – power from the battery is a priority, switching to the grid if the battery voltage is below the value in parameter 4)
02 50 Hz (output frequency, 50/60 selectable)
03 UPS (input voltage range from the network, UPS – 170-280V, APL – 90-280V)
04 23.0 V (if parameter 1 specifies SOL/SBU, then at this and below battery voltage the transition to mains power will be performed, 20-27 are available for selection, but not higher than parameter 14 and 35)
05 28.0 V (if parameter 1 specifies SOL/SBU, then at this and higher battery voltages the transition to battery power will be performed)
06 SnU (charging mode, SNU by default – hybrid charging from PV and grid with PV priority. When PV is not enough, then grid power is added, when PV is enough, then grid power is not used, it works only when the load is in bypass mode, otherwise if the battery is used, then only PV will charge.
CSO – PV is in priority, if not enough, then charging from grid.
CUB – grid is in priority, if there is no grid, then charging from PV.
OSO – only charging from PV.)
07 20A (maximum charging current, 60A by default)
08 LO8(LF8) (battery type, USE – custom parameters, SLd – sealed lead-acid battery (fast charge 28.8, float 27.6), FLd – flooded lead-acid battery (fast charge 29.2, float 27.6), GEL – gel lead-acid battery by default (fast charge 28.4, float 27.6), NCA – triple lithium battery (fast charge 28.4V), LF7/LF8/LF9 – Lifepo4 battery with 7 or 8, or 9 cells, LF7 (fast charge 24.8), LF8 (fast charge 28.4), and the maximum possible for my battery is 29.2, LF9 (fast charge 31.8).
09 28.2 V (boost charging voltage if USE or lithium batteries are selected in parameter 08). By default, 28.4, I did not set a large value, since there is no communication with the battery and when the battery is charged to 100% and parameter 37 is set incorrectly, then sometimes the inverter can give the maximum charging current (parameter 07) until the battery voltage rises to the value specified in this parameter 09, and at this point an imbalance in the cells and BMS alarms about overvoltage of some cells begin and this will be constant. If you specify a low voltage, the charging current will be lower than necessary, for example, at 28.0 V boost, the current will be 18A or lower, and not 20A as I indicated, the optimal value for my battery was 28.2 V, and at the voltage in parameter 37, boost charging is turned on when the battery is discharged approximately below 90%)
10 120 (maximum boost charge time in minutes when voltage reaches parameter 09 and if USE or lithium batteries are selected in parameter 08)
11 27.6 V (floating charge voltage when the battery is charged, my battery specifications say 27.6)
12 24.4 V (disconnection of the inverter output when the battery charge is low after the delay specified in parameter 13)
13 30 s (delay in seconds before inverter output is turned off when parameter 12 voltage is low)
14 24.8 V (low battery alarm, but inverter output will not be turned off)
15 24.0 V (battery voltage at which the inverter output will immediately turn off, without delays, the characteristics of my battery indicate 21.6, you also need to check with the BMS setting so that the inverter turns off earlier than the BMS, a good value is, for example, 3V per cell, 3V * 8 pcs = 24V)
22 dlS (power saving mode, default is off, when the load is below 50W, the inverter output will turn off and turn on automatically when it is above 50W)
23 EnA (automatic restart on overload, when the AC output is switched off due to overload, it will switch on after 3 minutes, after 5 overloads the auto restart stops and you will need to switch on the inverter manually)
24 EnA (automatic restart at high temperature, when the temperature is high and the AC output is turned off, it will turn on when the temperature drops)
25 EnA (sound signal for alarms, enabled by default, the sound is not strong, so I left it)
26 EnA (alarm when network disappears or appears)
27 EnA (automatic switching of the inverter to the grid (bypass) when it is overloaded)
28 20 A (maximum charging current from the network, 80 A by default)
30 1 (inverter number, used when connecting several inverters in parallel to indicate each one its own number)
32 SLA (SLA – RS485 port only for communication with computer, BMS – for communication with BMS)
33 PAC (protocol for communication with BMS, used if parameter 32 is selected BMS, available PAC=PACE, RDA=RITAR, AOG=ALLGRAND, OLT=OLITER, XWD=SUNWODA, DAQ=DYNESS, WOW=SRNE, PYL=PYLONTECH, SHO=FOX ESS, POW=POWMR, ixnfo.com)
35 27.2 V (when the battery is discharged, it needs to be charged to the specified voltage, only after that the AC output will turn on)
36 20A (maximum charging current from solar panels, 60A by default)
37 26.6 V (when the battery is fully charged, the inverter will not charge it until the voltage drops below the specified value, by default 26.8 for LF8, I reduced it, because when my battery was charged 100%, the voltage dropped to 26.7 and the inverter supplied the maximum current (parameter 07), until the voltage in parameter 09 was reached, and the voltage imbalance across the cells and alarms began. At 88%, my battery was 26.5V)
38 230 V (output voltage AC, default 230, available for selection 200,208,220,230,240)
