Solar Assistant and 6000XPs in Parallel

[Konvett]

I recently got my 6000XPs and I have them setup with Solar Assistant, but I don't think it's working the way it's supposed to.

From Solar Assistant:

With the 6000EX range SolarAssistant can read all parallel inverters when only a single inverter is connected. With the 3000EHV inverter you need to connect each inverter to the PI with it's own cable.

I would imagine this means that if I select a single inverter in the Inverter menu in Solar Assistant, it should be showing combined data for both. However, I have to select both inverters to get the combined view:


Is this supposed to be the way it's setup or should a single inverter selected show the combined data of both, the same way it does in the EG4 monitoring tool? The reason this matters to me is because in Home Assistant (I connected Solar Assistant to Home Assistant via MQTT), there is no combined load, PV power, battery power, etc. It's split by both inverters so I don't have a way to add a single meter that shows the combined values. Anyone else have this issue? Just set up the inverters so it's very possible I need to do something else within them. But I did set them up in parallel the way it's described in the manual.

You have to connect each one to Solar Assistant.

PS: you have the 6000xp, not the 6000ex.

You have it set up correctly.

@Konvett you can combine two photovoltaic (PV) sensors into a Home Assistant dashboard, you'll need to create a template sensor to aggregate the data from both sensors. Here's an example YAML configuration: you can add the template sensor to your configuration.yaml file. This sensor should combine the values of your two PV sensors.

template:
- sensor:
- name: "Total PV Watts"
unique_id: "total_pv_watts"
unit_of_measurement: "W"
state: >
{% set pv_sensors = [
states('sensor.pv_inverter1_watts') | float(0),
states('sensor.pv_inverter2_watts') | float(0)
] %}
{{ pv_sensors | sum }}
availability: >
{{ [
states('sensor.pv_inverter1_watts'),
states('sensor.pv_inverter2_watts')
] | select('!=', 'unavailable') | select('!=', 'unknown') | list | length > 0 }}

before you test the code in the developer tool replace sensor.pv_inverter1_watts and sensor.pv_inverter2_wattswith the actual entity IDs of your PV sensors.

use the developer template tool in HA to validate your code before you put it into the configuration file. after you put it in the configuration.yaml file you have to restart HA. Then use the total_pv_watts sensor in your dashboard or whatever.

same format works for adding any sensors together. I can give you more code snippets if you want to average the sensors like for SOC from multiple batteries etc..

Oh, duh... I can't believe how many times I must've read that and still not caught that. I get them mixed up a lot since I'm so used to saying EX (I just replaced them with the XPs).

On the inverter selection of SA, make sure you highlight ALL parallel inverters then connect.

Have you ever found a way to relabel each inverter in SA? It sort of arbitrarily labeled my inverters (1,2,3) in a different order than their physical order on the wall, so I keep having to (try to) remember which is which.

I never found a way to label or reorder the inverters in SA.

There is no direct way unfortunately. If you power off the inverters they very possibly will be reassigned. For months my two were backwards but after having them down for upgrades they came up correctly. You could try shutting down and bring them up one at a time and checking with SA. Of course it's easier with only two.
