Solarsmit

Good day guys. I have been reading up on the process of installing the new firmware, I am now confused, do you load the F2809... first or the F030? Because my process stays at Starting! 100sec passes and nothing happened. Tried WIN10 and WIN11, tried different cables. Only battery is connected. PV is not installed at the moment, load is disconnected. Where am I going wrong.

Good day, I have a client with a GROWATT SPF5000ES inverter and a 5.8kWh SOLARWISE battery, but the communication is not as what it should be. What protocol on the lithium setting must be used? I tried from 01 -09 and also 52, it keeps giving a comms error. The patch cable is correct. Any ideas.

Good evening, I have a GROWATT 5kW inverter and 1 x 3,5kWh Pylontech connected. The 150A circuit breaker trips intermittently. Do I change the circuit breaker to fuses? The inverter does not pull the utility in when the load gets a bit high, over 2,2kWh

Good day, I have a client that would want to get a SUNSYNK installed on his premises. I normally use GROWATT. The 8kW PV power, is it per MPPT or is it in total, both MPPT together?

Hi Richard thanks for the reply. Sorry I only answer now. It is a external MICRO CARE power limiter

Good day I have a client with a MICRO CARE inverter and a power limiter, there are about 4kW of panel power on the roof. When the power limiter is active then the power from the panels are decreased to about 500W. But when you disable the power limiter then the panel power increase to 3500W, but then the prepaid meter comes into effect and they pay for the solar power. Any suggestions?

Good day.I have a client with a Microcare inverter (Grid Tie),that is connected with a limiter,there is also a pre paid meter installed.The problem is that the limiter cause the inverter only to use 500W PV power and there is in total 3500W panels on the roof. When you switch the limiter off then the inverter uses as much PV power for the B&B,but then the power gets subtracted from the prepaid meter. Any suggestions?

Hi guys,I have a customer that has prepaid,i was thinking of taking his lights and some of the plugs off prepaid,Splitting his DB.What other suggestions do you have?

I downloaded Watch power, to my laptop.Running on Windows 7.But when I connect the USB cable to the inverter and to the Laptop then my laptop does not recognize the USB device. Any suggestions?I tried all of the USB ports but it give me the same message.

Hi there guys,I installed Watchpower and my Laptop does not recognize the USB device(Inverter) when I plug it in.I downloaded Watchpower 3 x now and still no luck,I want to setup the Pylontech US3000B.I went through the Growatt 5kW setup but it does not see the LiFePO4 batt.It goes into fault mode the moment I do the setup according to Growatt,try to contact Growatt,arrggg what a frustration. Please help

Good day.I have a Growatt inverter 5Kw, I want to use Watch power to communicate with the inverter but when I insert the USB cable then my laptop inform me that it does not recognize the USB device. What else can I do?

It is a client's installation.

I have also bought a GROWATT 5kW inverter.I struggle with the LiFePO4 setup.They state I must select the Li in step 5 then it jumps to step 36.There is a selection of Protocols,when I select the first protocol and change it from L0 2 to L1 2 then the inverter goes into a fault mode. Any ideas?

Thank you Coulomb.Then my calculations was correct.But the solar panel on the inverter does not show. I contacted MECER,waiting for an answer.Will keep you up to date.

Thanks for the info.But it still baffels me.I did the string calculations with the max PV inverter voltage of 145V and it indicated that I can use 3 max in a string. Question : Do you use the max inverter PV input voltage or the MPPT max V of 115V?

Good evening.I have the same problem with the MECER inverter as this gentleman.But my PV input V is 132,5V at the PV input on the inverter. i have 9 panels of 365W each, 3x 3 strings. 132,5V at midday.But no solar panels shows on the display,the setting for on SET 01 = SON.The 2 x 2.4kW Pylontech batteries also switches off after 5min.When I measure the Voltage at the Fuse Isolator terminals it is 49,99V, after AC is restored then the SOC on the Pylontech shows full(All green LEDS on).

Good evening,it is an AXPERT and it is Pylontech2 x 2.4kWh

Good day to all. I am surging for the best user friendly software to use as an installer to setup a customers inverter for the battery charge/discharge, must also be able to be selectable for most of the type of batteries. The customer does not need to monitor his system. I read up on the Raspberry Pi,my understanding is that the customer uses it to monitor his system!?

Good day,I have 2 x Pylontech US2000 in parallel.The "Master add dip switch 1 is on and the other 3 is off",The "Slave add dip switch is all off".Is that correct, then the Master has a alarm LED.What and how can I check what is wrong and how can I correct it? Sorry I forgot the inverter is AXPERT 5kW
