Use the Pylontech with LI 52 value in the Growatt settings and the BMS of the pylontech is taking control of your chargings if the packs are properly wired. never had any issues with mine, but as explained before if the voltage drops due to high loads the packs might go to an error state.
how much capacity is your UPS rated and which currents will be drawn and which currents can be delivered by your UPS continuously? From what you described it sounds your battery is not able to provide those high currents and the DC voltage drops down and makes the BMS think it´s in an error state...
which firmware are you using and are all packs at the same firmware? If you use CAN Settings are you using the correct protocoll in the BMS and the inverter? Are the cable pins as needed by the inverter and the BMS?
@sydzz you can use any voltage and voltage type you want up to 3A/230VAC. your manual will explain everything around page 11.
Yes P12, P13 and P21 have influence how and when the dry contact uses which contact situation, this is also explained in the manual.
you will not measure a voltage if...
my conceptual planning for a PV is based on the worst days/weeks in the year. To be honest this is not the cheapest version but the most sustainable one.
IF you need 10kW per night then plan your storage at least three times bigger. SPF5000 are fine as those devices are a great proof of concept...
for all out there with issues: you need to flash the correct firmware files for your model. The only indicator for the right firmware file is the firmware version on your device for end users/customers by today. Growatt might have more details but the label on the side of the inverter is not...
if your battery is not providing enough power the voltage will drop down and the battery or BMS will shut down the modules. Each inverter can draw at full power around 100A from the battery. I assume your tiny 14kWh storage will never support such a load. You have to consult first the battery...
I think the shine-f´s have a memory for storing offline data when there is no internet connection to the growatt cloud. I prefer my diy statistics version over the growatt cloud as the technicians from Growatt have full access to your settings at any time as soon you are online with the shine-f´s.
forget about growatt support. In Europe this is not present at all. Do it by yourself. google for amosplanet they provide everything you need for an firmware update. you can find manuals on youtube about upgrading the SPF series.
Yes I hardwired everything and disconnect my grid completely via an ATS from the inverter. This saves also a lot of standby energy and works great since months. I also added a logic which automates the shutdown of my second inverter in winter at night time or even the master inverter when the...
Update it by yourself is quicker and easier than ask Growatt for it. Why: The old firmware are buggy, even on the latest hardware versions Growatt produces. There are several minor and major issues known with the shipped firmwares that´s why a firmware update makes totally sense...
