Product Details
If you want a reliable and affordable generator for your off-grid applications, turn to the Xantrex PowerHub 1800 from Earthtech Products. This powerful solar generator will provide the all the power you need for off-grid cottages and cabins. It can be brought to large campsites to provide power for your group or used in other areas where you otherwise don't have access to electricity for convenient power. In addition to being used as a main power source when off the grid, the Xantrex PowerHub 1800 also makes an excellent backup generator for unexpected power outages in your home. That way, you won't have to run an expensive power source or worry about finding fuel for your generator when the electricity is out. And because it can be charged with AC power, solar power or wind power, it's one of the most versatile generator options currently available.

Simply install your SEALED, lead-acid Gel-type 12Vdc, 100Ah batteries into the provided battery box, connect the batteries to the PowerHub 1800 with the supplied cables, plug in the PowerHub 1800 into your wall outlet to start trickle charging your batteries. When a power outage occurs, simply plug in your appliances or devices into the PowerHub 1800. You can also connect solar panels and wind turbines to your PowerHub 1800 for alternate power supply to charge your batteries in the PowerHub 1800.

Welcome to the Xantrex PowerHub 1800 Installation Video.

Before getting started, Xantrex recommends reading both the user guide and installation guide thoroughly so that you can prepare for a safe and effective installation.

The first step before beginning any installation is to turn off the utility power to your house or cabin at the breaker box. The PowerHub will arrive at your house fitted with a flexible AC cord for easy connectivity to a generator but for a hardwired installation, the cover to the inverter charger must be removed. The flexible AC cord and plate must also be removed from the unit. The plate containing the flexible AC cord is replaced with a hardwire plate containing knockouts for hardwire input and output openings. Use the handle of screwdriver to pop out the access point for these and the knockout for the DC input cables from solar and wind inputs. The electrical code requires that DC input cables from solar and wind inputs must be housed in conduit as they run into your house from the outside where they originate at the solar panels or wind turbines, which are usually mounted on the roof or surrounding area. Once this is completed, the basic system is ready and able to be wired for hardwire installation to wind, solar and utility energy.

We begin with the wiring for DC inputs from a wind turbine. These originate from the wind turbine then go to a charge controller and then are directed from the charge controller into the inverter charger module where the black wire and red wire are connected to the appropriate terminals and tightened down with a ratchet set. Next, the wiring for DC inputs coming from a solar array can be connected. Here too, the wires come down from the roof top through a charge controller and into the inverter charger where again, the red and black wires are connected, only this time to the small ring terminals provided.

Now we must ensure that the inverter charger module is grounded to the main ground in your house or cottage by connecting the grounding wire to either the ground lug or by using a lock nut as shown here. Now that we have hardwired the DC inputs, we can begin to hardwire the AC or utility power directly into the inverter charger module. Here, we begin by loosening the AC input access point so that we can pull the conduit containing the white, black and brown wires into the module. Once this is done, we can begin to insert the white and black wires into the provided terminal block and tighten them into place. This is then followed by attaching the grounding wire, which usually requires making a hook with a needle nose pliers in order to ensure a good contact is made. This is followed by hardwiring AC power out by placing the black and white wire into the tunnel block and tightening them into place. With all of the hardwire connections complete, we can replace the top cover to the inverter charger module.

Now we are ready to install the battery box, which stores energy for the system. Once the top cover has been removed, lineup the holes on the side wall of the battery box with the bonding screws that protrude from the inverter charger module. Next, prepare to install the batteries by checking the cables and removing the protective plastic cover from the red positive cable. Then, carefully lift the recommended sealed lead acid batteries into place and lower them into the battery box one at a time. Then, using a ratchet set, begin to loosen the battery connections in preparation for connecting the batteries to each other and then to the battery box. Safety tip! Do not place your tools on top of the batteries. Using the supplied cables, connect the batteries together - black terminal to black terminal and red terminal to red terminal. Then connect the linked battery bank to the battery box ring terminal. Safety tip! Be careful to watch for reverse polarity. Red is always to red and black is always to black. Once this is complete, you can replace the battery box cover.

Some of you may choose to add a second battery box, which is available as an accessory. This second battery box allows you an additional 200 Amp-hours of energy by connecting two more batteries. Remove the blanking plate to connect the battery box to the inverter charger unit. Then, take the Anderson connector from the battery box and insert it into the inverter charger recess until it clicks into place. Then, using pliers snap off the plastic plate on the battery box and close the cover neatly hiding any of the wires. Safety tip! Ensure the battery box and inverter charger unit are bonded properly.

Once again, replace the battery box cover and the entire system is in place, properly connected and bonded together with both input power and output power in place. In this installation we have included the optional second battery box and we have chosen to hardwire an outlet elsewhere in the hall. In the kitchen, we have a hardwired outlet so that we can run key applications from the power supply by the PowerHub. Alternatively, AC power can be accessed without hardwiring through the 4 AC receptacles on the PowerHub. Having power is as easy as pushing a button. Instead of hardwiring the system, the PowerHub can also be used as a silent, powerful backup system when the flexible AC cord that we removed at the beginning of this video is kept in place and used to simply plug into a generator. Safety tip! Do not install the PowerHub outdoors because it is only designed for indoor use.

from San Jose, California asked:
June 19, 2017
We are not off the grid, however, we do have solar panels installed on our house. Is there a solar generator that can be used when our electrical systems go out which is compatible with our PG & E as well as the solar panels for backup. Thank you, Bevorly Cain-Berk
1 Answer
The Large Grid Tied systems cannot be used with off grid applications as they rely on the grid for a complete circuit. When the grid goes down, it leaves the solar panels rendered useless, as they cannot store the power created. The Off-Grid systems we offer connect the solar panels to a battery back up which stores the power for emergency use. Thank you for your inquiry!

from Corpus Christi, Texas asked:
May 19, 2017
Will this powerhub 1800 battery backup run a chest freezer that runs on 2 amps 115 volts but has a 12 amp startup and for how long (with the 2 - 100 amp batteries)?
1 Answer
The Xantrex PowerHub 1800 Battery Backup Power Storage does not include any batteries and is simply the inverter and battery box combination. If you were to add (2) 100 AH batteries that can be found here: The system would operate for roughly 35+ hours until the batteries were drained down to around the halfway mark (best battery maintenance practice). This time frame would vary based on the amount of times the chest freezer is opened during operation, due to the motor coming on and off. Thank you for your inquiry!
