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 15kW  48v Inverter for Tesla Battery Modules
1 of 10
THE MOST POWERFUL 48vdc INVERTER IN THE WORLD 

Battery powered off-grid systems are quite 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 38v.  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 38v 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 15 kilowatt inverter made in China that can do 45kw for 20 seconds.  It charges at 110 amperes from 240vac.  And we have commissioned them to provide a Low Voltage Cutoff of 38vdc and a charge limit of 50.5vdc - ideally tuned for the 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.

Enphase Diversion Loads Manager
1 of 7
 The EVTV Enphase Diversion Loads Manager is a standalone WiFi device that communicates directly with your ENPHASE ENVOY data gateway device via your home WiFi Router/network to obtain operational data on your Enphase solar power system.
It features FOUR switched MOSFET outputs that can drive four external relays at 12v and up to 3 amps each.  In this way, you can switch on and off diversion loads such as water heaters, hot tubs, EV charging, etc. based on the output power of your Enphase solar arrray.  

Additionally, it will also monitor our Tesla Model S Battery Monitor/Controller for similar data allowing outputs to be swtiched based on voltage, current, or SOC of your Tesla Model S battery module battery pack.

Explosion Proof 20kw Off-Grid Inverter
1 of 2
 This 20kw True Sine Wave off-grid inverter features a very rugged explosion proof enclosure which was designed for use in mines. But the result is it is extremely resistant to weather..  It has been modified to take our frequency shift input to shift the frequency between 60.0 and 62.5 Hz to shut off grid interactive inverters when the battery reaches 100% state of charge. 

It also works perfectly with our Tesla Model 3 battery and controller with a 300-400vdc input and a 240VAC split phase output L1, L2, and N common in the United States.  Simply wire into your loads panel with a 100Amp circuit breaker and turn off the grid.
