50kW Inverter for Tesla Full Battery Pack
1 of 7
 We had this 50kW Inverter designed specifically for the full Tesla Model S battery pack.  It uses a wide high voltage DC input range of 280 to 450 vdc to produce up to 312 amps of 240vac 2 phase power for U.S. applications.  L1, L2, and N with 120vac on L1 and 120vac on L2 - 240vdc total.

This inverter will do 50kW (208 amperes) continuously and 75kW (312 amperes) for up to 10 second surge.

With an 85kWh Tesla Model S full pack and our EVTV Controller for Model S full battery pack you can store sufficient power for most U.S. homes for nearly 3 days and nights.

And better, it is simple to operate.  No massive configuration list.  In fact no configuration except for the front panel where you can select between 50 and 60 Hz output.  That's about it.  Large, easy to read front panel meters provide readouts for voltage, current, power, and frequency at a glance.

It also reverses the usual battery backup scenario.  Normally, grid AC is passed through an inverter and on loss of grid, the inverter kicks in to produce AC from the battery.  This inverter reverses that.  Normally, the inverter produces AC power from the battery, and in the event the battery voltage is lost or below 300v, it changes state and passes AC from grid or generator through to the loads.

10kW High DC Input RackMount True Sine  Inverter
1 of 8
 A 10kW 240vac/120vac isolated inverter for use with a Tesla/Volt/Leaf full battery pack.  This device is amazing.  First, it works from a high voltage DC input of 200-500vdc - perfect for an EV battery.  Second, it has an AC output to match U.S. power panels with L1, L2, N and ground.  This means two 120vac output circuits and a single 240vac circuit - exactly like your power panel.  And yes, it is a true sinewave inverter.

It fits in a standard 19 inch rack mount just 10 1/4 inches high. It uses a heavy quality copperlow frequency  transformer totally isolating your AC side from your DC battery.  Clear readable front panel LCD allows you to set your low voltage cutoff to whatever you like (typically around 300v) to prevent overdischarge of your battery.  But it goes high enough (500v) to handle initial surges from high voltage photovoltaic arrays.  And at a price typical for a 5kw inverter. And it will do 15kW for 5 seconds to start even the largest air conditioning load. NOT GRID TIE - off grid inverter. 94% efficient.

Magnum 48v DC to AC Inverter and Battery Charger
1 of 6
 This is a 48vdc Battery Back up power system and offers the best features we've found in its class.  It supports a DC input voltage of 36 to 68 vdc and provides BOTH 120vac and 240vac split phase outputs.  Rated for 4400 watts, it will produce up to 8000 watts briefly and 4800 watts for up to 30 minutes with 4400 watts continuously.  Up to 70A surge output on the AC side.

36kW MPPT Solar Charge Controller for Tesla Model S Battery
1 of 5
 There are now over ONE BRAZLLIAN different weeny cheap charge controllers in the solar market.  ALL of them are for 24/36/48 vdc and do less than 3 kW.  Worse, ALMOST all of them allow a Photovoltaic Arrary input of a MAXIMUM of 100 or 150vdc.

And almost all currently grid-tied professional solar installations use PV array strings of 400 to 600 vdc.  This allows the use of smaller cables and less line loss on longer cable runs.

We had this controller designed specifically to charge the Tesla Model S full battery pack at up to 400vdc.  And we insisted on a PV array input maximum of 750 vdc.  Bettter it features a whopping 36kW of power putting out up to 100A at 360vdc to your battery.  That means you can FULLY charge a Tesla Model S 85kWh battery pack in less than 3 hours of sunshine.

It's the most powerful solar charge controller we have seen.  It has the highest max PV input voltage.  And we just can't find anything to charge a battery to 400vdc.   Not just at this price point.  At ANY price point.

It's simple.  It's powerful.  And it's selfish.  It does one thing, and it does it very very well.

Flexible Solar Panel 200w
1 of 8
A 200 WATT SOLAR PANEL UNLIKE ANY YOU'VE SEEN

 This lightweight, high efficiency solar panel is unusually well suited to electric boats, aircraft, RVs and  electric vehicles.  Here's why:  

LIGHT WEIGHT at just 3.3 kilograms - 7.275 pounds each.

VERY THIN - just 3 mm (0.118 inches) thick and built on a very durable flexible acrylic sheet.  This means you can mount it on curved surfaces up to 30degree bend with minimal wind resistance.

VERY HIGH EFFICIENCY -  cell efficiency  20.8%.  While the panel is made in China, the individual cells are made in the Phillippines  by SUNPOWER using their MAXEON back connect technology for very high efficiencies

So for example, you could build an array of 10 sheets that would weigh just 75 lbs and put out 2000 watts - a truly useful amount of energy.  You could actually charge an 20kWh pack in 10 hours - about two days in the sun.

GENUSUN WATERPROOF 105-350W 56.8V LITHIUM BATTERY SOLAR CHARGE CONTROLLER
1 of 2
Marine Grade.  This is a very unusual charge controller in that it can charge a battery of a HIGHER voltage than the solar panel output that feeds it.  In this way, you can charge a nominal 48v lithium  battery pack to a precise 56.8v using a solar panel that puts out 33v at its maximum power point.  This is the only device we've found that will do that.

We had these specially made by Genusun in their waterproof casing - fully potted and in a plastic enclosure.  This will last forever in marine/boat applications as well as golf cart canopies or other outdoor in the weather applications.

This one is designed to charge 16 LiFePo4 cells to 56.8v using a Constant Current/Constant Voltage charge curve perfect for our LiFePo4 cells.  

But it can do it from ANY of our flexible solar panels - a single panel. 

Why?  Put a single panel on the roof of your golf cart or the deck of your john boat and use this to charge a 48v battery pack at up to 8 amps.  It could not be simpler.  We haven't seen anything else out there like this "boost" charge controller device.

Flexible Solar Panel 120w
1 of 3
A 120 WATT SOLAR PANEL UNLIKE ANY YOU'VE SEEN

This lightweight, high efficiency solar panel is unusually well suited to electric boats, aircraft, RVs and  electric vehicles.  Here's why:  

LIGHT WEIGHT at just 2.45 kilograms - 5.4 pounds each.

VERY THIN - just 3 mm (0.118 inches) thick and built on a very durable flexible acrylic sheet.  This means you can mount it on curved surfaces with minimal wind resistance.  About 30% deflection is possible.

VERY HIGH EFFICIENCY -  20-23%.  This panel is made for EVTV in China using a special laminate. But the individual cells are made in the U.S. by SUNPOWER using their MAXEON back connect technology for efficiencies up to 24%.

What this means is that you can put solar panels in places impractical before.  The lightweight, thin, flexible panels can be attached to RV roofs, boat decks, canopies, and places where the usual 45 lb stiff framed glass panels would simply be absurd.

And since real estate on these "vehicle" applications is limited, paying for the extra efficiency of these superior cells actually makes sens

AC Solar Lightning Arrestor
1 of 3
LA302R  A solar "must have".  This lightning arrestor is a high power silicon oxide varistor capable of shunting up to 100,000 amps of current in 10 nanoseconds.  In placing solar panels on the roof, we are basically setting up a "lightning rod" to actually attract lightning during stormy weather.  Then we connect sensitive electronic components to the lines.  This is a recipe for disaster with thousands of dollars in charge controllers, batteries, inverters, along with computers and other devices plugged into the system.

This device attaches easily to any panel box and connects between the AC power lines and ground.  In the event of a high voltage/current surge, it very quickly shunts that energy to ground - saving your other electronics.
