Growatt SPF 5000 ES Firmware and settings to validate


Recommended Posts

Posted (edited)

Hi everyone,

 

I would really appreciate it if someone can provide me with the following:

  • Latest firmware for SPF 5000 ES
  • Latest firmware for the MPPT
  • Latest firmware for the data logger
  • Latest version of the ISP Tool
  • Documentation for the above

I would also like to know your opinion about the current setup and its configuration that I have although I have confidence in the person who installed but I would like to double check if the settings are good enough to keep my batteries efficient and durable.

The setup is as per the following them as per the following:

  • 2x SPF 5000 ES running in parallel (firmware: one inverter is 040/041-05-701 and the other 040/041-06-104)
  • 10x Longi LR5-72HPH-545M (each 5 panels to an inverter)
  • 12x Lento lead acid LSTB-22000 (12V 200Ah) - installed each 4 in series (48V 200Ah) and then the 3 series in parallel resulting in a setup of 48V 600Ah -> 28.8 Kwh
  • The whole system is also connected to the utility as well.

My inverter settings are as per the following:

Program Description Value
1 OPPR SOL
2 CHGI 70
3 ACV APL
4 SAVE DIS
5 BATT USE
6 LDRS DIS
7 TMRS DIS

Your cutoff voltage is on the low side, unless you don't mind risking a reduced lifetime of the batteries.
Here is a table for typical 12V Lead-Acid chemistry. Multiply those by 4 and decide if you wish to remain in the green band. That would be the suggested cutoff V.

Have a look at this thread. All your other questions are answered in there, including the downloads and files you are looking for.

Thank you so much for your help.

Can you please also check setting 2-12-13-18-19?

2 I would leave as is seeing that you are running 12 Batteries
12 I would recommend 48V to ensure the Batteries start charging once they reach 12V
13 - 18 - 19  Leave as is

One question. Why are you using "USE" Battery type instead of "FLd" ?

Oh, by the way, i ddnt mean setting 18. Instead, what do you think about #20?

 

I didn't setup my devices, the installer did. I'm not sure why he is using USE instead of Fld. But in any case, if I use Fld, what would be the default settings in this case? do I rely on the default values or do i also need to change them?

Default Fld would preset the typical Leadacid Battery settings. You would still be able to adjust some of them but some may be fixed. USE mode allows you to set everything manually. Perhaps your installer had a look at your specific battery data and decided to rather set everything manually.
You basically know what your settings are now, so no harm in setting it to flooded and then you can cycle through the program codes and compare what the default settings are.

20 should be whatever is shown on your batteries as being the recommended float voltages. Normally something like 13,5 to 13,9V (obviously needs to be multiplied by 4). It differs by manufacturer but it is normally printed on every Flooded or AGM Battery. 54V or slightly lower would be my recommendation.

Would the updated files be ok in South Africa? Or aren't these inverters region bound?

As far as I can tell, no, they are not region bound. I was sent the .05 files directly from the International Rep in China. Never updated my inverter to .06 as it is working just fine for me.

zsde can you send the new firmware to me please? Onmy growatt everything works fine untill I suddenly start pulling a big load from pv, then the inverter cuts off the solar completely even though there should be enough power to pull the loads.

For that Battery you should be able to use the "FLD" setting, I think you can only change battery types if the inverter is in standby mode ( switched off at the bottom rocker switch)

how do you mean " understand" your battery ?

in terms of "state of Charge" these inverters only sense the battery voltage and do a best guess from there, a Victron BMV 712 or similar energy meter should give you a much better idea of battery capacity and state of charge.

sidenote : Where does one find these forklift batteries, or locomotive single lead acid cells for a decent price ?
