To build this rig cost under $300 aud I'm fairly impressed with it. There was 90ah so about 2kwh pumped into the HWS & for me to buy that 2kwh of energy from the grid it would cost me about $0.50cents so ROI would be 600 days - would you do it for that ROI?
Costs would be even cheaper if you had some old solar gear laying around!
3 used 250w panels - $120
Some DC Cable, YBranch Connectors & MC4's - $30 ebay.to/2Iu6fZe
DC/DC 100a relay & Heatsink $55 ebay.to/2KIgNGG
600w 24v DC hotwater element - $35 ebay.to/2K5aVIk
10yr old 50l hws - $30 ebay.to/2F3fcHV
Add the cost of a few copper pipes & fittings and you have a sub $300 hot water system that'll last years and provide about 50lL of hot water per day.
