Furpile's Solar System

[furpile]

Details of my install setup to be added to W@P's list.

8kW Sunsynk
2x Hubble AM'2's (with space for another 2 in future
16x 460W JA Solar panels (8x East and 8x West)

Since then I have added SolarAssistant to better manage the loads from HomeAssistant. Still some way to go to be able to control more heavy appliances and aircons.

Best day after install in July 2022 produced 22 kWh in Winter. Now in Summer production has reached 49 units if I am able to use all of it (mostly afternoon production is wasted).

Congratulations!
It's like that space was made for it.

are you able to run the aircons on this set up during the day

No reason not being able to,8Kw is plenty

@W@P another one for your index.

Definitely. Still planning a door or something between that and the kitchen to damp the fan sound a bit. But for now it works well.

thank you. I am busy looking and want to be able to run 100% solar during the day including aircons

 

[furpile]

Yeah easily. During the day currently the solar peaks at more than 6kW so there is plenty of power to run anything. See this post for what it looks like maxing out (almost) the system during the day. Summer with full sun you really struggle to use all that power that is available. Could use a couple more batteries for sure.

The only aircon that is tricky is the 36000 BTU (old LG non-inverter) that is in the flat. It runs at 3kW most of the time, but the startup current is quite high. Can't run it during loadshedding or it trips the inverter on overcurrent. With grid available no issue though. Inverter aircons also make it much easier.

Inverter aircons are the way to go if you don't have any yet. Much lower startup current than traditional and the power use is constant. Normal aircon caries between fan only and compressor running, so you have constant spikes to max power. This makes managing all the loads a bit more difficult than having the aircon just run at a fixed lower power.

Here's an example from yesterday.



Red: pool pump from 9-3 + 2 geysers on + ac + base load
Green: 1 geyser + base load + ac
Blue: pool pump from 9-3 + base load + ac (occasionally turned off when it got too cool, but mostly turned on).

8 kW is the one to go for if you don't want to monitor usage. It can even go beyond 8 kW for short periods like above...

Non-inverters are a bit harder on startup and can exceed the limits sometimes. My 9000BTU units haven't tripped my house yet but YMMV

Done

 

[W@P]

This is mine with a 12000 BTU running the whole day as well as 2 geysers from 12:00 and the base load. The Midea I got sips power. Unreal.

 

[W@P]

Then I got another 2 x 24000 BTU Samsungs that also run without any issues.

Inverter aircons ?

 

[W@P]

Inverter aircons ?

Yes

 

[Tabac]

Yes

So a question from an AC noob. How does an inverter aircon use less power ?

Aircon differences for Inverter usage:
Inverters - Start the engine,slowly go through all the gears 1 - 5
Normal Aircons - Start,put gas to the floor and spin wheels till there's traction


Aircon differences for "less power":
Inverters - accelerate and decelerate as necessary to set point
Normal aircons - Start stop start stop start stop to set point

By keeping the compressor running, and just varying the speed. It'll use a constant 1 kW or whatever depending on BTU.

Non-inverter will constantly shut down and restart the compressor, drawing high load whenever it starts up...
