Explosion Proof 20kw Off-Grid Inverter
1 of 2
 This 20kw True Sine Wave off-grid inverter is just fun.  It doesn't make any sense pricewise unless you need the explosion proof rating to operate in mines, dusty areas, aluminum powder areas, or other places requiring an explosion proof enclosure that won't expose any sparks or arcs to the environment.  But the enclosure winds up being very rugged with huge external heat sinks to dissipate the heat without the usual airflow.  So the result is a super heavy, super industrial look in a very heavy duty very high qaulity iindustrial 20kW off-grid inverter.  We HAD to have one.  And our viewers might have an application where this is just the thing and justifies the expense.

The side effect of course is that what can't get out also can't get in.  And you have a super environmentally resistant enclosure.  This one of course designed to use electric vehicle/Tesla full battery input voltages.

PowerSafe100
1 of 9
 The PowerSafe 100 is a 100kWh Solar Energy Storage device with 15 kW DC-AC pure sine wave inverter/charger and a complete battery management control and display system.

It is a complete OFF-GRID AC power system with a 240vac power output of 15kW continuous and up to 45kW surge in the standard U.S. 240vac L1, L2, Neutral, ground four wire output that can be wired into any standard loads panel.

It does NOT work with the utility grid but you can use grid (or generator) INPUT to recharge the batteries.

Better, it works fantastically with grid-interactive solar systems, replacing the grid and will actually recharge the batteries from your grid-tied inverters and solar panels.

This is NOT UL listed although it is compliant and is intended for stand-alone power applications.  It uses 20 Tesla Model S battery modules for energy storage.

Sigineer 12kW  48v Inverter for Tesla Battery Modules
1 of 8
 Battery powered off-grid systems are quiet popular and 48vdc is the current voltage of preference.  Unfortunately, most 48vdc inverters are simply a poor match for Tesla Battery Modules.  Why?

The main problem is the Low Voltage Cutoff - the point of battery discharge where the inverter will shut down to protect the battery.  Almost all 48vdc inverters have LVCO in the 42-44v range with a very very few able to handle batteries down to 40v.

Two Tesla Battery Modules in series are pretty much discharged at 36v.  but they are only 50% discharged at 43.2v.  And so with almost all inverters on the market you are leaving 30-50% of your battery capacity on the table.  That means you have to purchase TWICE the battery capacity that you would need if the inverter simply operated down to the 36v cutoff.

The other issue is that many of these inverters will also charge your batteries from AC - the charger is built in.  That's great, but they are traditionally designed for lead acid batteries.  They may support a bewildering array of Pb chemistry types, but ALL of the charge curves they provide are deadly to Tesla Battery Modules.  We advocate charging with a simple bulk current to 50.5volts and NO MORE.
Almost all inverters want to charge to something more like 56 volts with equalization phases as high as 60v.  This will immediately DESTROY your Tesla Battery Module, not over time but the FIRST time it does so.

And of course most 48vdc inverters provide 4kw to 8kw of power max.

We have located an excellent quality 12 kilowatt inverter made in China that can do 36kw for 20 seconds.  It charges at 110 amperes from 240vac.  And we have commissioned them to provide a Low Voltage Cutoff of 39vdc and a charge limit of 50.5vdc - ideally tuned for the Tesla Battery Modules.

Sigineer 15kW  48v Inverter for Tesla Battery Modules

With the 15kW model, we introduce a set of FREQUENCY SHIFT contacts.  When used with our ESP32 Battery Module Controller, this lets you easily turn off grid tied inverters used to backcharge your batteries through the inverter when the battery gets full.

DC Solar Lightning Arrestor
1 of 2
 LA602DC 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 solar lines and ground.  In the event of a high voltage/current surge, it very quickly shunts that energy to ground - saving your other electronics.

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 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.

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

Solar Surge Protector
1 of 3
Protect your system from lightning strikes with the Midnite Solar Surge Protective Device (SPD). Designed for both AC and DC solar electric systems, it provides protection to service panels, load centers, or where the surge protector is directly connected.
 
Designed for both indoor and outdoor use, the SPD is offered in three different voltages—115, 300 and 600 volts. Protection is achieved by reducing the clamping voltage to a safe level that your system can sustain and that won't damage electronic components.
 
This Midnite Solar surge suppressor is a welcome replacement to arrestors that have been used in the past. Providing eight times the protection as previous arrestors, it is much better at clamping surges to a safe voltage.
