Hi,

 

Two years ago we put a 5.3Kw solar array on the roof of our house.  We have spent two years running around turning on and off various appliances, water heaters, a pool pump and the Jacuzzi as solar power was available.  Luckily we work from home and are around most of the day to do this.

 

I am tired of running around switching things on and off and want to develop a smart controller to do this automatically.

 

If any of you have a solar array you might tell me what to do to maximize the use of the available solar power automatically?

 

Any suggestions would be welcome.

 

 

 

Regards,

I'd be checking if someone else has already done the hard yards integrating your inverter model with Home Assistant.
This sounds like the type of thing you're after?

At a minimum you should have a solar diverter for hot water installed, so any excess energy goes towards your HWC. Assume you have also minimized your power usage by replacing all lights with LED too.

Thank you for your reply.

 

That system relies heavily on you having a battery.  With a battery it is a lot easier to capture the available power and not waste any sending to the grid.

 

We do not have a battery as they are still very expensive and require a special battery charger.

 

Regards,

Solar Diverters do not require a battery to work, on the contrary they are more of an alternative to running batteries (expensive)

 

You get paid diddly squat sending back to the grid, so a diverter setup to feed excess power to your HWC will be highly effective, as heating is one of the larger costs of powering your home.
