Some States are absolutely nuts on ground source heat pump regulations. In Idaho there's no special regulations (AFAIK) on open loop ones. Take water in (from a well or city supply) and dump it in the open, down a storm drain or into a body of water, or put it down another well. Seems rife with possibilities for contamination. But if you want to install a closed loop system that *seals away* the working fluid from the environment and ground water, that's when you get into some complications. I think they have their regulation priorities backasswards.
Alternative/renewable energy setups tend to go about things in a 'one thing does all' system where all the energy is collected from one source (like a huge PV array) then stored in one place (a single, large, battery bank). then they have a complicated system to convert voltages and AC and DC etc to all the end uses. To me that's just crazy. If you're using sun tracking (for PV or solar thermal) don't tap the energy for the tracking system from the collector. Install a small PV panel on each collector (or for small groups of them) so that the tracking power and control is completely independent from the main collection. Same for any liquid or gas pumping needs. Put in little PV panels to run each pump. Split up the battery bank so there are sections optimized for each type of load, at least one optimized for lighting (which for off grid should all be low voltage LED) and one for the high power stuff like heating and cooking appliances. Then you won't end up running out of heating power by running the lights, or you'll still be able to nuke a burrito (and keep it frozen before nuking) even if you're out of light power. The different battery banks could be configured for easiest conversion to the needs of the loads drawing on them. The energy collection could likewise be segmented to match each battery bank. Then you'll have a system that won't ALL go down if one critical component fails. If a sun tracker on one collector conks out, then that's *one* collector out while the rest still work. If the power converter for the light battery dies, then you're only out your lights instead of *everything*. Put all the components on a wall like this guy has his network equipment, label everything. Tour of my home network. | | | | | | | | | | | Tour of my home network.

As to 12 volt only temporary and mobile systems should be 12 volt, that's why I'm at 48 and would go higher ify in Stock equipment would allow, it's also why I will be running a 22 horse Lister diesel. I agree going off grid is hard , I have been at it 5 years. And can't overstate reduction of necessary power is absolutely key. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
