  • DIY Off-Grid Solar System V2.0

    I agree, very informative & clear details, better than I could ever do. I will add the following that may be of interest...1. Please consider the potential for fire propagation when mounting power products on wood board, it is worth doing a risk assessment.2. The life of lithium battery is also dependent on how much time it is at full charge, not just the discharge depth cycle. I charge my LiFePo4 to only about 80~85%,(CC chg only) this ensurer's longer life (saving $$$).3. Longer cables to inverter have higher inductance, this can put more ripple current stress on inverter capacitors shortening life. It is best to always keep short as possible.4. Lithium battery like being less than full charge, this is ideal for some cloudy days when a full recharge is not possible. (lead batte…

Lithium battery like being less than full charge, this is ideal for some cloudy days when a full recharge is not possible. (lead battery don't like being discharged for extended time)5. Lead battery has a fairly long tail current (slowly reducing Amps in CV chg mode), I charge my LiFePo4 battery with full current up to full (~80%), then stop & divert PV current to water heater.Keep up the good work

  • You Can Use a Drill Bit for More Than Drilling Holes!

    You can also make a bit into a counterbore by grinding about 20mm of the OD to the size of the holes you want to bore & square the cutting edges with some clearance angle.This is useful if u have a 'do it now' job.The shaft makes good dowel pins for metalwork as it is strong but not brittle like the fluted section.

  • Just did a search & the wrong preview image is showing up in the results, The correct one is ok in the instructable, its the one with Thanks

    Thanks, it is ok now wait.. Only issue now is it only show up as draft when I click on my head (image below)...One thing I noticed when I was editing there ended up multiple instances (not separate but seemed layered on top) of my draft instructable.not sure what caused this.
