Below are the detailed specifications of our inverters 4K 120-volt  This 4000 watt inverter charger produces a pure sine wave, which some appliances require for use. So it can run laser jet printers, computers, televisions, CPAP machines and other medical equipment. During a big storm that knocks out electricity, a battery-bank and power inverter running a sump pump could be the difference that saves a home from flooding. The power to run a heater could save someone thousands of dollars by keeping plumbing pipes from freezing. Also great for emergency backup power applications is the automatic transfer switch on this unit, which keeps the power supply uninterrupted in the event of an outage. With the inverter hooked up to shore power, it will detect the loss of electricity and start pulling energy from a connected battery bank instead to keep the power supply constant. This inverter also has an optional remote port, allowing you to turn the product on and off from a distance. Click here to purchase the remote. Other popular applications for this inverter include powering lights and other appliances in an off-grid cabin, providing electricity for a mobile business or mobile office, and running camping equipment.     4000 watt low frequency inverter     12000 watt surge for 20 seconds 300% surge capability     Battery Priority Selector     Terminal Block     Marine Coated and Protected     Multi Stage Smart charger 100 Amp     remote panel available     auto frequency     10msec typical transfer time     optional 25W power save mode     7 battery type settings for charger Inverter Output Specifications:     Continuous Output Power: 4000 Watts     Surge Rating: 12000 Watts (20 Seconds)     Output Waveform: Pure Sine/Same as input (Bypass Mode)     Nominal Efficiency: >88% (Peak)     Line Mode Efficiency: >95%     Output Frequency: 50Hz +/- 0.3Hz / 60Hz +/- 0.3Hz     Typical Transfer Time: 10ms (Max)     THD: < 10% DC Input Specifications     Nominal Input Voltage: 12.0Vdc     Minimum Start Voltage: 10.0Vdc     Low Battery Alarm: 10.5Vdc-11.0Vdc     Low battery Trip: 10.0Vdc-10.5Vdc     High Voltage Alarm: 16.0Vdc     Low battery Voltage Restart: 15.5Vdc     Idle Consumption: <3.47 amps DC     Power Saver Mode Idle Consumption: <0.53 amps DC Charger Specifications     Output voltage: Depends on battery Type     Charger Rate: 100A     Over Charge Protection Shutdown 15.7V     Selectable Charge setting based on battery type     Adjustable charge current off-20%-100%     Four Stage Smart Charger Transfer Switch Specifications     40 amp automatic transfer switch     10 ms (max) Dimensions     Unit Weight: 64 lbs.     Unit Size L x W x H: 23.5 x 8.75 x 7.10 inches     Shipping Weight: 75 lbs.     Shipping L x W x H 30.5 x 14.25 x 13.75inches Top of Page 4K 240-volt US     4000 watt low frequency inverter     12000 watt surge for 20 seconds 300% surge capability     120/240 Vac output Split Phase(/li>     Battery Priority Selector     Terminal Block     Marine Coated and Protected     Multi Stage Smart charger 115 Amp     remote panel available     auto frequency     10msec typical transfer time     optional 25W power save mode     7 battery type settings for charger Inverter Output Specifications:     Continuous Output Power: 4000 Watts     Surge Rating: 12000 Watts (20 Seconds)     Output 120/240 Vac - Split Phase 50 or 60hz     Output Waveform: Pure Sine/Same as input (Bypass Mode)     Nominal Efficiency: >88% (Peak)     Line Mode Efficiency: >95%     Output Frequency: 50Hz +/- 0.3Hz / 60Hz +/- 0.3Hz     Typical Transfer Time: 10ms (Max)     THD: < 10% DC Input Specifications     Nominal Input Voltage: 12.0Vdc     Minimum Start Voltage: 10.0Vdc     Low Battery Alarm: 10.5Vdc-11.0Vdc     Low battery Trip: 10.0Vdc-10.5Vdc     High Voltage Alarm: 16.0Vdc     Low battery Voltage Restart: 15.5Vdc     Idle Consumption: 50 Watts     Power Saver Mode Idle Consumption: 21 Watts Charger Specifications     Output voltage: Depends on battery Type     Charger Rate: 115A     Over Charge Protection Shutdown 15.7V     Selectable Charge setting based on battery type     Adjustable charge current off-20%-100%     Four Stage Smart Charger Transfer Switch Specifications     40 amp automatic transfer switch     10 ms (max) Dimensions     Unit Weight: 64 lbs.     Unit Size L x W x H: 23.5 x 8.5 x 7.0 inches     Shipping Weight: 75 lbs.     Shipping L x W x H 30.5 x 14.5 x 13.75inches Top of Page 5K 220 Volt EU     This 5Kw modified sine power inverter has a 12 volt input and a 220 volt 50hz output.

Sun Direct’s batteries come with terminals and cables for inclusion in our systems. Our batteries are each 7.5"x11"x10". Weight 77 pounds.  Power Packs use the same batteries. When you order batteries from us, or when you order a system which uses batteries, we have those batteries delivered to a Battery dealer in your area.  It is then your responsibility to go pick them up; they'll be waiting with your name on them.  You do not have to pay for those batteries when you arrive to pick them up; you paid for them as part of your order. This ensures that your name is on the warranty, so you can claim warranty service at any of hundreds of nationwide locations, should the need arise.  It also spares you the expense of shipping batteries, which incur Hazardous Material packing and shipping charges.  Trust us; you don't want to pay someone to ship a battery to you.  You want to go to a store and pick it up.
