Monitoring Sofar Solar + RS485

MariuszAK · May 19, 2023, 12:12pm

Uruchomiony kilka dni temu zestaw paneli fotowoltaicznych zintegrowałem z moim HA.

Falownik:

SOFAR 6.6KTLX-G3
Wersja sprzętowa：V003
Software Version Number 1：
Wersja protokołu：1.08
Software Version Number 2：0
Software Version Number 3：0
Master Software Version：V020004
Software Version Number 4：0
Vice Software Version：L020004
Standard Main Version：0606
Wersja oprogramowania procesora komunikacji：G020002

Zaistalowany logger wifi:

Wersja modułu nr：LSW3_15_270A_1.53
Extended System Version：V1.1.00.0F

Do podłączenia falownika z własną siecią LAN wykorzystałem RS485 TO ETH (for EU)

Po uruchomieniu konfiguracja modułu.

Temat zrealizowany dzięki wydatnej pomocy @RobinI30 , dziękuję

PS. Z falownikiem można się także komunikować za pomocą loggera wifi, w mojej wersji softwarowej, za pomocą flow zaczerpniętego z tego wątku

Świetna robota. Gratuluję dokładności.
Sam od kilku dni posiadam ten falownik, ale o mniejszej mocy, tj. SOFAR 5.5KTLX-G3.
Wersja logera jest identyczna, nieznacznie inna jest wersja softu falownika. Odczytuję dane bezpośrednio z logera poprzez NR. Dlaczego zdecydowałeś się na RS485 TO ETH (for EU)? Jednocześnie odczytujesz jeszcze jakieś dane z licznika? No właśnie… w jaki sposób odczytujesz użycie energii?

MariuszAK · May 19, 2023, 3:21pm

Połączenie po “kablu” zdecydowanie uważałem za pewniejsze. Czytałem, że są problemy z odczytem w zależności od wersji loggera, nawet jak teraz “czyta” to po ewentualnej aktualizacji może przestać, dlatego też wybrałem konwerter.

Nie, nie mam podłączonego licznika do inwertera. Używam Zamel Supla MEW-01 do odczytywania importu i exportu energii.

m4r0n · May 22, 2023, 8:02pm

Też zastanawiam się nad zakupem tego właśnie licznika. Mam pytanie o encję promieniowanie słoneczne i intensywność światła, a mianowicie z jakiej integracji skorzystałeś? Czy jest to może Forecast.Solar?

Dariusz_Barczyński · May 22, 2023, 9:31pm

Tu macie gotowe rozwiązanie w NR dla RS485 TO ETH
mam ustawiony odczyt danych co 5 sek. dodatkowo Sun uruchamia od wschodu do zachodu co nie generuje błędów

Cześć

Czy będzie to chciało współpracować z

Edit:

@MariuszAK Cześć, czy to jest jakaś gotowa integracja?

Tak to jeden z wielu sposobów na zintegrowanie falownika z HA. Opisuję jak i czym go zintegrowałem.
