Mike's (non-Sunsynk) System

Bring your pool pump to an earlier day slot as to not eat into eskom and battery.

Yeah I've changed it to 12:00 - 16:00. So 4 hours once a day, rather than 5 hours split over twice a day that it was previously set...
 
If we take the pool pump out of the equation it looks like your post 6pm load is around 500-800W. So you with 50% SOC you should get from 6pm to about 2am on a decent night... If you pushed SOC to 30% you might even push it all night.. cool experiment to run :)

Yeah that's the plan eventually :)

Started with 50% as a baseline. I need 15% for load shedding and can't go below 20% because my DOD on the batteries is 80%. So theoretically I should be able to go as low as 35%...
 
Optimizing everything is the fun part. I now use 2 to 3 units a day from Eskom and sit with 50% SOC by 8:00 in the morning.

Could in theory run my geyser from the batteries at 5:00 in the morning but I prefer prolonging the lifespan of the batteries instead.

R100 a month to Eskom isn’t a problem.

This is where i want to get to as well - getting a 2nd and possibly 3rd battery should help -along with more PV.
 
Production has been decent today considering it's been overcast.

The spikes of blue are because the battery has been discharging and charging due to the weather, but also because of the increase loads of the pool pump, kettle, microwave etc...

Thanks for this thread.

I really like the idea of putting a deposit down and financing the rest, like paying off a car. But instead of the world's worst asset which just depreciates the moment you buy it, this solar install just pays you back money from day one...

100%

Many people are realising the value of solar now more than ever.
 
I am eyeing the full system off the grid via fnb rewards! Still reading up and comparing...

I'm sorry but in accordance with being part of the solar tribunal you are required to show your stats 5 times a day, this is your first notice of breach of the brotherhood.
 
General question (maybe a daft one): if your inverter is 8kw and therefore can handle maybe 10kw, does that mean your maximum load at any time can never exceed 10000W? What if you turn on all your appliances and that runs to 12000W? Does it just explode? Or pull the excess capacity from the grid / batteries?

Sunsynk 8kW will pull in from the grid for up to 11kW (50A). 5.5kW can go up to 7.7kW (35A)

It trips, do it a couple of times and it will trip and never come back up.
