Just purchased a few of these micro inverters, has anybody successfully integrated them into HA?
I am looking for a way to limit output across them, based on house demand, so that I can limit the total export.
At a later date they can be wired into a new solar inverter, but I don’t have it yet.
I already have a number of Wi-Fi CT meters reporting consumption and export in HA
I use this HACS integration:
I also have a Stream 4622 microinverter. Unfortunately, it doesn’t currently support any form of control. Fortunately, I use it in combination with PowerStream, so I’m using a hybrid control system via PS, with the Stream controlled through a smart plug. It’s not ideal, but it’s the only solution for now, and the automation is very complex to prevent unnecessary cycling and overfeeding into the grid. I’m also hoping that the Stream 4622 will receive an update that adds control capabilities.
I think I will end up wiring them into a new grid tied inverter, which has an aux/microinverter input port. That way it can limit total house export.
me too, its good
Thanks all.
Now installed 2 of these microinverters using the HA integration and working well.
I actually have them plugged into a smart switch, so it would be possible to use HA to turn off the switch if way too much electricity was being exported.
I am fortunate as I already have a G98 in place for an existing MCS solar array, as long as I keep my total export below its capacity there should be no issue. Currently completing a G99 with G100 for an additional inverter and batteries.
Here is 1 of the microinverters monitored in HA:
Hola yo tengo un microinversor ecoflow Stream. Con las API oficiales solo puedes leer sensores, pero ahora estoy utilizando BLE ecoflow (no oficial) que permite también ajuste. Concretamente el control de inyección. Eso sí, tengo un shelly 3em pro que mide el consumo de la casa y debido a que la respuesta de el control del microinversor es lenta, no funciona bien para una gestión en tiempo real. Yo tengo también una batería y una automatización que cuando la batería llega al 95% reduce la inyección de microinversor a 100w que está por debajo del consumo de la casa y si la batería llega al 85% vuelve a poner la inyección al Máximo 800w. Para mí caso funciona muy bien.
I’m working on supplementing my powerwall 3 with a diy battery bank, that I’m using a stream micro inverter cover lighter loads saving the powerwall for higher wattage loads. I have the inverter going into a dedicated 20 amp circuit. The problem I’m running into right now (may be more seasonally caused as not running HVAC right now) but the 2 legs of my panel are not staking close. So I’m going to pick up a second stream micro and ad another dedicated circuit and outlet for it on the opposite leg, both will feed from the i 48v battery bank.
I’m using the ble integration: https://github.com/rabits/ha-ef-ble and the control is much quicker than the cloud, output power adjust within a few seconds.
I have a Span panel so I can just control an integrated relay to turn the output from the stream off or on. It does fake a good 3-5 minutes for it to come one and then start pushing AC.
Will you connect the STREAM microinverter to a DIY battery instead of solar panels? How are you planning to charge the battery?
I posted a bit about the project on mastodon here: TubesZB: "While recovering from back surgery and in between…" - Mastodon
Batteries are charged with separate charges. Right now I have 2x 1 kW chargers and 1x 500 W charger that I use with a ecoflow delta 3 pro in the mix too. Everything is tied to the same 48v copper bus bars and the chargers are controlled by zigbee plugs with power monitoring. I wait until my powerwall 3 is charged or is charging with significant excess and selectively charge the battery bank with the various chargers anywhere from 200W via the minimum from the delta 3 to about 3.7 kW max when all are on.
I picked up 2 ELTEK Flatpack HE 48vx2000W power rectifiers that can be controlled with ESPHome over CAN and will be integrating those as well. I also have a Victron MPPT I will use when I get some additional panels - mainly to charge separate the main solar system.
When charging or idle I adjust the micro stream inverters to 0 output (for some reason I had that 200W was the minimum and would use the Span switches for the circuit each was on).
Yesterday was a good solar production day so everything topped off early. weather is coo enough to not use AC so overnight usage was not too bad. today is cloudy and rain and It still may be able to top things off. we had a string of rainy days over the weekend and I wasn't able to keep up.
Right now it's in a proof of concept phase. with the 1kWh Delta 3 + 2x Wattcycle 5120 kWh.
Additionally I have 4x 12v 3.84kWh batteries that will go into series and be added to the bank. This will involve a full rebuild and add fuses and breakers to get things into a much more safer state from the current "proof of concept" phase. After that I hope do a detailed write up here.
The DC to AC to DC conversion for charging the batteries is not ideal, the ELTEK will become the main chargers I think and they should be more efficient.
I have a shelly plug uk gen4 and in settings you can change it to input. I then plugged Invertor into that and used for meter for solar Input
After trying to install this integration, either from the links posted here or the HACS repository already built in, it keeps failing to set up with this error
