New Member here 8kw Deye/ 12kw PV /7.6kwh back up

Recommended Posts

Hey all 

Been reading the forums here for the past few months now 

Just had my solar installed done on the 17th of Dec a few pics to follow as well 

1x8kw Deye Hybrid inverter 
30x400w BYD solar panels
40x1.2V 198ah Nickel-iron batteries (DIY build and super cheap)
Pre-paid power as a back up as well

Only thing I do not like atm is the solarman smart app and its 5min delay. Is there a way to see this info live like looking at the Deye screen on the inverter?

My next step is to replace my 150L Geyser 3000w element with a 200L/275L heat pump Geyser (some thing like this https://www.acdc.co.za/pages/product-individual?EMS-TH200DT)

Any advice would be greatly appreciated

Eventually the perceived need to have data quicker than 5 minute intervals falls away. You don't really need it any faster than that to be fair.


What's wrong with your geyser?


I have a 4kw 200L geyser that I can't see the point of replacing. Smart load starts and stops the geyser for me perfectly without any effort whatsoever.


You have a boatload of panels, I have half the panels you do and I almost always have excess solar capacity.


You might find that you need more batteries, that seems to be the common realization I've found.

I have an Efergy that I watch the mains power on and if I could have that for both Pv ports and battery that would be amazing (like on the Deye display)

Nothing wrong with the Geyser as I did not split my DB I have the whole house on it and if we run everything at once we just over 8.8kw on the Inverter so with replacing it I could run everything at the same time and be under 8kw

More Batteries would be amazing maybe 4x https://lithiumbatteriessa.co.za/collections/diy-kit/products/48v-16s-100ah-lifepo4-lithium-ion-phosphate-diy-kit

I can't offer advice as I don't have any technical skills appropriate to what we discuss on this forum, but I can share some experiences.

Some time ago I had a heat pump installed. At the same time I had a good quality blanket fitted to the geyser. I run it on the timer switch. It comes on line at 6:30 in the morning. It runs for about 45 minutes to heat all the water in the geyser. For most of that time it is drawing about 1.4 kw. There after it runs for much shorter periods to keep the temperature up. It draws so much less than a conventional geyser that we can keep it on the backed up circuits.
