LPG does it better: With LPG as an additional fuel source, you get way more flexibility. When the grid is down, it's ideal as an emergency option for your home or RV as gas is hard to come by. Not only that, you can store it longer, produce 10% the carbon monoxide, and create less fumes and scents. 
 
Huge capacity for extended blackouts: With a 1600W-1800W*1 output and a 4L gasoline tank, you can generate 5.4kWh in gasoline or even 20kWh with LPG*2. That gives you hours up to 12.5 hours of runtime with LPG alone. Connect that to your DELTA Pro/Max to charge up when you’re all out of other options. All while using less fuel, producing less noise, and producing fewer emissions. 
 
Save fuel. Maximize efficiency: When paired with DELTA Pro/Max, you'll get a 40% efficiency gain, saving you fuel, producing fewer emissions, and charging your batteries.That's down to direct DC-DC charging (10%) and X-Stream Charging tech (30%). With that, you can charge DELTA Max to full in 1.8 hours, or DELTA Pro is 2.7 hours. 
The efficiencies don't stop with charging either. Pre-determine a set battery percent and automate the Smart Generator to turn on. It'll recharge your DELTA Pro/Max, then shut down when full.
 
Stay powered even while charging: While recharging your batteries, you can still use the AC sockets to power other essential AC appliances simultaneously. If both your AC and DC ports are in use, it’ll intelligently prioritize your AC supply to keep powered no matter what. 
 
Real-time monitoring and control: Once connected via Bluetooth or WiFi, the app opens up a whole world of possibilities. Set your battery level for auto-start, control DC output levels, remote start or stop your unit, and switch on Eco mode, all while getting a full suite of monitoring and alerts. Up close?
