Hi from Aotearoa
#1
Hi guys,

I am from Pegasus a small town north of Christchurch New Zealand.

I have been watching and reading and learning about energy storage for about 3 years.

I have a 9KW solar panel setup 12kwh of lead carbon storage (which is great) and two electric cars (both Nissan Leaf) our family of 5 are petrol free! Such a good feeling.

I have started to crave more energy storage and stumbled on a rather large supply of free 18650 cells! Barely used and 3000Mh capacity.

I am going to aim for the sky and try to build 60kwh of storage. It’s obviously not going to happen overnight and I may do a video blog to document the process.

Sheet metal fabrication is my background but no training in electrical so trusting a sparky mate of mine and the community to guide me.

But, you've already got at least 60kWh of storage, is 9kW enough to keep that topped up ?

9kw should be enough - i run with 4kw on 40kwh of storage if it runs down takes a few weeks of good days to get back to top of charge tho

I could barely believe my luck! although after watching some of your channel HB I dont know if I would call building a powerwall lucky!



In summer i get paid for power, autumn and spring is very cheap and winter is still expensive. I am running a 6 gpu mining rig also which demands power.

Our hot water is evacuated tube in winter its a double edged sword with little solar thermal energy and too little photo voltaic energy.

60KWH is the goal but anything over 40 would be pretty helpful.


Yea the house is pretty low E. Although I really want to work myself away from ANY dependence on grid energy. I am even thinking about building a small turbine in my yard! hahaha.

believe me, I am already talking with my solar panel supplier about upgrading 12 panels to higher outputs. the key is being able to charge a leaf overnight if possible. with 2 and work hours its frustrating to be burning power off all day only to have a car come home and struggle to charge it!

I need bigger north facing roof lol

We have 1.5kW facing due west - can highly recommend it as it protects the batteries from load for 1-2 hrs of an afternoon after the sun has moved on from the north facing panels...  only during summer ofc...
