Blinkwater9 Posted April 18, 2019 Share Posted April 18, 2019 Hi to all. Jürgen from a small coastal village on the West Coast of the Western Cape, StHelena Bay. In the last 2 years, I have gone completely off-grid on my water supply, maybe to the extreme? LOL. Next is the electricity supply? Stumbled onto some CANADIAN SOLAR Polycystaline 335w panels a few weeks ago. Next is to do a detailed data logging of the current electrical consumption(750kwh/month ave). Acquired an EFERGY unit I will be installing this weekend. My plan is to design the system to built in 2 phases. Phase 1 will be a 5kva HYBRID Inverter with battery back-up, and phase 2 will basically add an addition 5kva. I need the inverter to supply PV/BATTERY first, and fill in any shortfall with UTILITY GRID power. Any advice will be appreciated. Thanks.

jasonvanwyk Posted April 18, 2019 Share Posted April 18, 2019 Awesome Jurgen! I cant give any advice because I'm so new at this, but one of the best things i discovered was the ability to measure what each device appliance is using (by use of an efergy / kill-a-watt / sonoff etc). I've been able to cut back on so much of my usage/wastage and really get my batteries to last longer through the night. Quote Link to comment Share on other sites More sharing options...
Blinkwater9 Posted April 18, 2019 Author Share Posted April 18, 2019 Thanks Jason. I know that monitoring equipment is frightfully expensive, because I own about half a bars worth of compressed air auditing kit. The price of the efergy stuff was rediculously cheap by comparison. I run 3 pumps to produce my household water: a 750w centrifugal wellpoint pump, a 600w rotary vane HP pump and worst of all, a 1,55kw booster pump to drive the pressure for the house. At the least the booster pump has a VSD, which will even out the surges. The 3 pumps add up to 3kw alone. But at least they dont run all day. My plan is to log the house load over 8-days, and see what that looks like, before I purchase an inverter. Quote Link to comment Share on other sites More sharing options...
