In this episode we test the ENphase IQ7x grid-tied microinverter and 96 cell Panasonic panels to determine if they can be used to charge Tesla Battery Modules using our 12kW off-grid inverter to provide the necessary 60Hz sinusoidal waveform.

We also introduce a new project to outfit our 1990 Volkswagen Dopplekabine pickup truck with Tesla Drive Unit to serve as a Solar Electric Smartphone charging station for an upcoming local music event.

  1. I would like to apologize to Jack's audience for what has turned into a totally unproductive banter back and forth between Jack and myself. I do have concerns, I do believe UL 1741 has purpose and that we all need to build and install electrical systems safely and according to codes and laws. Jack and I are simply unable to debate our differences in a positive manner; as such I will withdraw and leave everyone at peace. Good luck to everyone including Jack; a brilliant if not stubborn man.

  2. So Jack, Utility Troll Moron here. Are you going to answer my question? Is you system wired as shown in your diagram, with your battery inverter output and shop load tied together on the load side of your transfer switch?

  3. So Jack it seems your clever system really makes the Loads panel do a lot of clever stuff. I take it that you are truly almost completely independent. That is sensible.. to my mind. I would have thought it will pay for itself over the long haul. So your experimentation is interesting. I use Enphase and a string inverter but that is because I have an old legacy system which is still pumping in power plus some Enphase powerd panels. But Microinverters, their AC power and their cloud based software allow the average guy to keep taps on what one is using and what one is making. you can beef up your system without changing your string inverter ! In Australia, with my Grid tied Powerwall 2 I usually have a very small electricity bill. I believe my Powerwall 2 will be paid off in 7..5 yrs (based on usage savings and Grid input credits) . So my AUS $11,000 battery is pretty great addition for my purposes to my mind. I believe you are correct about the motivation of a lot of Electricity company as being based on fear of loss of revenue.. Always informative . I like your perspective …

  4. Brilliant observation of the monopoly electric utility industry. Getting out from under this little "tyrannical" fact is worth an extra 10's of thousands of dollars to me.

  5. The lads took the truck for a spirited spin today. The panels do NOT wave in the air or rattle around. Everything is sound, snug, and tight. No rattles. We parked it out and make a couple hundred watts into the 12v. Outback works great and shows both voltage and current in and voltage and current out. Very stable. Good battery regulation right at 13.6vdc.

  6. Excellent video and promotion of Enphase's latest-greatest, the IQ7X, which in collaboration with Panasonic, gets them into the 96-cell panel arena. Mr. Rickard — don't mean to pry, but I know nutrition well; my advice to you is to take a shot of apple cider vinegar at night for the next few months so that you can lose the toxic waste you are carrying. Good luck and God bless.

  7. Jack Rickard  After more thought, your system can never operate safely connected to the grid. You're battery inverter introduces a synchronous power source. If you have your system operating and you open your main breaker to the grid, your battery inverter continues to supply your shop and your grid-tied inverters continue to operate synced with your battery inverter.
    Now, go down the street 2 or 3 houses and cut the utility powerline. You and your neighbors continue to be powered by your solar and batteries. Still at 60 hz and 240v (7.2kv if the primary is cut). Now, your soccer mom neighbor and her 9 year old son Timmy are the ones that drove into the pole, causing the 7.2 kv powerline to fall into mommy's car. Little Timmy opens the car door and steps out, AND BAM, little Timmy is dead, FROM YOUR BATTERIES AND SOLAR! But hey, it's all just a conspiracy by the power companies. I'm sure you will win that argument in court.
    The only safe way to do what you are doing is to use a transfer switch to open the utility connection anytime your battery inverter is powering your shop. This is why transfer switches are used for emergency generators. The problem with a transfer switch is that you will experience a short power outage every time you switch back and forth between your batteries and utility.
    Jack, you are a brilliant man, so think about it! What you are doing is very dangerous.

  8. Why not put some (a couple) Tesla battery modules for extended late night charging in the "yellow bumblebee cellphone" truck for enhanced and buzz-worthy backup power generation during the concert?

    Also, what about putting some large RGB LED matrix sign displays on the sides of the truck for concert related messaging, digital signage advertising and even add SMS based concert attendee messaging?

  9. I have been try to think of a way to use the AC inputs on this inverter with microinverters so the batteries can charge with the built in battery charger. So the inverter won`t blow up when the load goes over 12 kw.

  10. One more 12kwh inverter test to do lets see what happens when you start loading up the inverter. I have seen a sigineer 12kwh smoke when the load got over 12kw when back feeding and charging.

  11. Come on Jack! There is no conspiracy going on! I have designed and built over 200 inter ties with utilities over the past 38 years. These are primarily hydroelectric plants ranging from 10kw to over 100mw. I can assure you there is a risk, not only to linemen, but also your neighbors down the street. A car clips a pole and a powerline falls on a car, a kid steps out and gets fired! Your batteries and solar could kill someone. All you have to do is install inexpensive relaying to separate your systems in the event of islanding. Also your 240v is stepping up to 7.2 kv at your service pole transformer. Thus arcflash is a real hazzard too. It's not a conspiracy, it's very cheap safety which I say is required. You a disseminating incorrect information which could get someone killed. All based on "conspiracy theories" that do not exist!

  12. Jack, be careful with your arrangement. I love what you are doing but this system poses a risk of back feeding a dead utility bus. The fact that you are syncing the grid-tied inverters to your battery inverter, if your batteries and inverter keep the solaredge inverter live, and you are also closed to the grid, a separation down the line could continue to feed a downed power line. The solution is an intertie protective relaying scheme. These are simple under/over voltage and under/over frequency relay. If you try to carry a separated utility load, voltage and frequency will vary, tripping the intertie relay which should be set to open your tie to the utility. Basically I see you are defeating the grid-tied inverter (anti-islanding) protective function.
    I admit it is very likely your system will be overloaded or shorted out, tripping your breakers. But utilities mandate protection from back feeding.

  13. Why were the inverters made to 500 watt instead of the 600 watt rating of two panels so 1 inverter could connect
    2 panels ? This would be more cost effective and the added components would add very little cost.

  14. Is there no way to disconnect the batteries after they have reached their cutoff voltage and just let the load draw what it wants from the solar? It seems like this would help prevent a lot of unnecessary wear on the batteries.
