Battery has been sold.

Thanks @PsyWulf, I unfortunately don't have a USB-RS232 cable on hand nor used PBMSTools. I can look at buying the cable to get the SOH and cycle counts as it should help with the sale. Do you have a link to the exact cable to possibly get? Thanks.

Item: Hubble AM-2 Battery Age: Purchased in July 2021 from the PowerForum Store. Was in use from August 2021 - January 2022. Price: R19000 Payment Method Accepted: Cash / EFT Warranty: Yes, remainder of 10 year warranty Packaging: Not original Condition: Excellent Location: Midrand, Johannesburg Reason: The Hubble battery was paired with my Sunsynk 5kW inverter and 12 solar panels during the period of August 2021 to January 2022 (6 months). I then sold my property without the system. I temporarily rented whilst looking for a new property and in this period, the system was in storage with the hope to install once I move to a new place. Battery was topped up to maintain SOC. I've now found my new place. There is an existing system in place at the new house however with a different battery manufacturer, hence the sale. I'm not sure how to check cycle count with the battery not currently connected however it should be very low due to only being in use for 6 months.

Hi @Saliegh Yes, you can add those variable declarations and you should be good. I also needed to add those two variable declarations with one of the versions of the flows I downloaded.

Thanks @RhysMcW I've updated to 2021.9.4 Now I see the PV and Grid selections in the Energy configuration. I guess it's a waiting game until data starts to populate,

What Home Assistant version are you guys on? I'm currently on core-2021.8.8

Thanks, I've added the mqtt discovery to the yaml config, restarted but still unable to see the entities. I will try to restore an earlier system backup and try again.

Thanks. I've removed it completely and also added the state_class rule to the energy nodes (7 in total), I also double checked my Assemble Config node and the settings correspond with using an underscore, I've restarted everything however still don't see the sensors in the energy drop downs.

@Sc00bs would you mind sharing what your yaml file entries look like? I currently have this in my configuration.yaml file, homeassistant: customize: sensor.sunsynk_grid_gridbuy_day: device_class: energy state_class: measurement sensor.sunsynk_solar_pv_day: device_class: energy state_class: measurement however I still cant see/select the sensors in the Energy settings. Thanks.

Hi @JeremyJvR You need to download two additional nodes that are not pre-installed with NR. Click the hamburger icon on the top right corner > click Manage Palette > Click Install tab. Search and install the following two nodes, node-red-contrib-cycle node-red-contrib-moment That should resolve the issue.

Thanks @Sc00bs and @Bloubul7 It was related to InfluxDB settings. I've updated the InfluxDB settings with my user credentials and the data is flowing into InfluxDB, Now I just need to get the Grafana dashboards to pull the data, Edit: Figured it out. Needed to add an additional data source for the "InverterDB" database in Grafana. Thank you kindly, gentlemen!

Thanks @Sc00bs Progress...I dont get the same error but get the following debug errors repeatedly, Inverter status flashes between active/queueing repeatedly as well.

Thanks for the response @Sc00bs My Node Red settings are below, Inverter Node Settings: MQTT Settings: I've changed them to my MQTT server

Hi All, I have a question regarding the ethernet cable and connection to the inverter. I've connected up an ethernet cable wired as T568B into the BMS RS485 port on the inverter. The other end of the cable is then wired up, orange/brown&white - A, Orangewhite/brown - B into this USB-RS485 connector , followed by a USB cable into the Raspberry Pi4 (running Home Assistant, Node Red, InfluxDB, Grafana, MQTT) So the flow is, T568B Ethernet Cable in BMS RS485 port on Inverter > Into USB-RS485 connector > USB Cable > RPi4 When looking at the modbus-flex-getter settings in Node Red, I don't see any options to select the USB in the serial port (clicking the Magnifying Glass) When looking at the debug, the modbus-flex-getter node cycles through states of, Client Not Ready To Read At State reconnecting Error: Client Not Ready To Read At State init Am I on the right path or is there something else that could be fundamentally wrong with the cable, config etc? Any help will be much appreciated. Thanks.

Thanks @YellowTapemeasure Much appreciated.

So looking at the inverter specs, It has a max DC input voltage of 500V, MPPT range is 125-425V and Start Up Voltage is 150V The Jinko Tiger Mono panel specs below, 460W (STC) Vmp 43.08V Imp 10.68A Voc 51.70V Isc 11.50A 6 panels equate to 310.20V which is within the operating range for the inverter with some head room to expand on that string should I add a panel or two. I've also input the panel specs in the PV String tool and the results are attached. Does this look feasible? Many thanks, daWolf

Really valuable feedback. Thank you guys. I am in Midrand, Johannesburg area. I do have a bit of calculations to do in terms of panel choice.

Thanks for the feedback thus far. Got some reading to do on the string size calculations

Hi All, Newbie checking in here, I'm planning the installation of a Sunsynk 5kw Inverter, 2 Pylontech US3000C Batteries (3rd on the horizon), and looking at 6 to 8 panels to start with. The plan is to have the geyser, oven, one aircon (24000 BTU) on the non essential circuit with the rest of the house wired up. I have an energy monitor and I do not see usage spikes greater than 5500W which includes a 3kw geyser (not on a timer). Other high usage appliances like the microwave, kettle, airfryer, dishwasher, washing machine, hairdryer etc. never really get used all at once. If I exclude the geyser from my base load and include the occasional spikes with the various appliances used, its usually peaks around 3500W. In terms of solar panels, I've been reading about the Jinko brand and their Tiger series seem to be rated well. Their Tiger 460W Mono panels seem to be priced well and I am wondering if 6 of those panels would match up to the Sunsynk 5kw inverter in terms of voltage, VOC etc. Again, complete noob with these terminology here but hoping to gain some valuable input and advice before making any decisions. I do not have a lot of North facing roof and can install 6 north facing panels. If I do expand at a later stage , panels would need to be install with an East/West split. Would you recommend those solar panels or should I consider something else altogether? Is 6 panels enough or start with? Any and all advice is welcomed. Many thanks.
