Recommendations for System Monitoring Program for SOFAR KTL-X 4.4 Inverter 3.3KW Installation

Question

I have a new 3.3KW installation with SOFAR KTL-X 4.4 inverter What system monitoring program can your colleagues recommend to work with this inverter?

3301 · Answer

solarmanpv.com/portal

Tech132 · Answer

I recommend pvmonitor.pl.

MichałS · Answer

Pvmonitor is tailored to Polish realities. Literally sewn because many options can be agreed with the admins for which they are praised

krzych101 · Answer

I have Solarmanpv.com, but he does not show me my consumption, and as for pvmonitor.pl
from what I read, I would probably have to have some additional device that would transfer data from my inverter to the website

3301 · Answer

No load energy flows through, for example, the house, so the inverter of this load does not flow through the currently installed inverters. he does not see, to control the consumption it would have to be an additional meter, but the solarman will not see it anyway
Lancontroler, meter and pvmonitor would do it, or a dedicated meter for the inverter and probably only fronius and steca offer such

MichałS · Answer

The easiest way to register consumption is from a diode on a 2-way counter.

krzych101 · Answer

And you can write more clearly on whether this registration should rely directly from the meter diode? Added after 2 [minutes]: What is this lancontroler?

3301 · Answer

Go to pvmonitor, shop

krzych101 · Answer

I was typed lancontroler but found nothing

3301 · Answer

Approx. here it is called a counting and sending module, it is LK but with software specifically for pvmonitor, and you need consumption, so focus on monitoring production and consumption

krzych101 · Answer

And there is some software besides solarmanpv that works with the SOFAR inverter and Wi Fi datalogger because I would like to use the equipment

3301 · Answer

I only did the solarman, moreover, if you register it here, it is not anymore, as for inverter monitoring through this program, there are many parameters there to read without additional expenses
If you absolutely want consumption, you can also separately or pvmonitor or readings physically from a two-way meter or from an additional sub-meter that you will assume

krzych101 · Answer

Will I use PVMONITOR to read data from my SOFAR inverter without this counting and sending module?

MichałS · Answer

I recommend reading: Link

krzych101 · Answer

There he writes that this counting and sending module was supposed to cost PLN 50 and today it costs PLN 250 and it is in addition a wired connection, so I would not have to ruin the apartment to get the cable from the inverter to the router

bzag · Answer

you don't have to, just install a wifi router with AP client function, which will connect to the wifi network, but it's better to ruin the apartment and connect the cable - less radiation ....

krzych101 · Answer

I have an inverter on the router but I am looking for good software to work with the inverter

orawczyk · Answer

Colleagues, I have a question. I have two installations, one on a zeversolar inverter, the other on a solar sofar, in which program I can monitor both. I don't want two apps

theo33 · Answer

Probably a pvmonitor would do it, with an extra meter or two if they are to be monitored separately

rafaelo2 · Answer

All you need is the solarman smart sofara counter app for about PLN 750 and it looks like this

krzych101 · Answer

But PLN 750 for an additional meter is probably an exaggeration just to look at yourself. Probably the naive will find themselves

bioly · Answer

Hello, Lan Controller overlay Modbus and beautifully monitors Sofara. I recommend

krzych101 · Answer

Maybe a colleague elaborate on the topic by providing more details?

bioly · Answer

You can monitor such inverter parameters in real time, Lan Controller refresh is set to 0.5 sec by default. Write what you need to know, I will say if it is possible

theo33 · Answer

As my friend knows the topic, I would also ask what elements needed to connect sofara with pvmonitor? is the cheapest PVMterminal WiFi Slim enough? or maybe there is something else cheaper

SilverX · Answer

SDM630 Modbus from China for PLN 260. It is also worth adding an RS485 logger for PLN 20 to Sofar. You will have everything within your LAN. I recommend getting interested in Home Assistant.

toolpusher · Answer

And is there a step-by-step tutorial on how to assemble, program and run it? @ Theo When describing this Slim, he says that he does not support inverters.

SilverX · Answer

Link As for the SDM630, take a look at the Tasmota software. At the beginning, an RPi 4 or a terminal with a quad-core processor is enough for the Home Assistant.

krzych101 · Answer

I see SDM630 for over PLN 300 with shipping plus a loger, that's as much as the Supli meter with Wi-Fi, unless you have cheaper, then provide a link
