Powerhub 1800 Operation Guide

Appliance & Device Run Times

Frequently Asked Questions:

Q: Will this Solar Generator run my entire house?
A: This Solar Generator is not a whole house system, whole house systems can run anywhere from $40,000 - $100,000 and is typically only for reducing energy costs on your electric bill and not for back up power. This kit is designed to run essential items such as Refrigerator, freezer, computers, laptops, lights, cell phones and other electronic devices up to 1800 watts at a time! So this kit is definitely the ultimate in back up power in case you experience a power outage.

Q: Does this solar power kit for home use come with everything I need to get started?
A: This Solar Generator comes with the solar panels, DC Combiner Box, Charge Controller, Inverter, Batteries and Solar Panel Cabling, you will only need purchase cabling at your local hardware store to run from the DC Combiner Box to the Power Hub 1800 since every application length is different. It is important to consult with the electrical supply store regarding the gauge recommended for the distance you want to run in order to avoid a voltage drop, we can also assist you with this information.

Q: Do I need an electrician to install this emergency power solar generator?
A: You do not need an electrician to install this solar power backup generator if you will be plugging your devices directly into the PowerHub. If you want to hook the system up to the electrical panel in your home, you will need to contact an electrician for installation.

Q: Does this kit come with a mounting rack or hardware to install to a roof?
A: Since every customer's application is different, we do not supply any mounting hardware. We often recommend for roof applications to purchase Z brackets from a local hardware store and they simply mount to the frame of the panel and roof. Many customers will also build a simple rack for the solar panels to place in the backyard when others will simply lay them out in grass. The options are endless.

Q: Can the PowerHub Inverter and Battery Boxes be left outside?
A: No they cannot. The PowerHub and Batteries should be kept in a cool, dry location where the temperature does not dip below 32F nor exceed 100F.

Q: How long will it take to charge the solar backup generator kit in a wall outlet?
A: It will take approximately 16 hours to fully charge the system from a wall outlet.

Q: How long will it take to charge this solar generator with the included (4) 265 Watt solar panels?
A: When exposed to 100% direct sunlight, it will take approximately 5 hours to fully charge this solar generator.

Q: What types of ports does the inverter have?
A: The inverter has 4 AC outlets on the front of the unit, underneath the LCD Display Screen.

Q: Is the PowerHub 1800 computerized?
A: Yes it is. The LCD digital readout screen exhibits input and output power, battery level information and the amount of power available to charge the batteries.

Q: Will this solar powered generator power a heater?
A: Yes, this will power a standard 600 watt portable space heater on low for approximately 8 hours.

Q: Will this solar power generator system power a 110 volt sump pump and if so, for how long?
A: Yes this will power a 110 volt sump pump. For example: A 1/2 horsepower, 110 volt sump pump would be able to run for up to 5 hours with this unit.

Wasnt waiting until the grid went down
August 23, 2015
I was worried about the US grid going doen and having no power. I searched the web for a solar generator and I kept coming back here because they seemed to specialize in these and I was happy that i went this route because im all set up good to go. The folks here were great and assisted me with figuring out that this one was the best solar kit for my needs. I like to have more than less is why I went with this one.. Had a blackout since and it worked great for me. My wife thanked me for my manly buy.
  • Fairly easy to set up
  • None
Best UsesBack up emergency power, run an efficient fridge and freezer, lights, phone

Great idea
January 10, 2017
I really liked the concept of this system: 120volt stand-by power, self sustaining thru solar panels, piece of mind. It took me almost a year to install the system, even though I am an elec. contr. there was a learning process. I found ETP to be extremely helpful with installation questions, technical support, and operational information. What they couldn't answer they put me in contact with someone who could. The equipment seems to be of high quality and delivery was good. I am currently testing the system to be sure it can perform and run house hold items. I highly recommend this to everyone buying any similar system. Also highly recommend safe guarding roof mounted solar panel wiring as squirrels think the cables are yummy
  • self sustaining power, no gasoline powered generator, no noise,
  • limited supply of power/wattage, which is acceptable
Best UsesResidential stand-by power

Great product but installation a challenge
November 7, 2015
We live in a rural area where power goes out often. Also concerns of a more widespread power outage and grid going down. We have a back up gasoline generator but wanted this as an additional back up, especially if gasoline in short supply. Concept of the unit is very good. I was disappointed though in the lack of comprehensive instructions. Even though we got individual instructions for each component, we did not get a complete set of instructions for the complete system. We eventually hired an electrician to complete the installation. I would have like a very detailed comprehensive installation guide for the entire system and all components.
Merchant Response:Thank you for your feedback! The installation instructions and operating guide are located in the Powerhub 1800 packaging portion of the bundle. Plus there are some helpful videos here to show you the general set up. If you are not familiar with connecting low voltage (12v) positive and negative wiring, or looking to do a more elaborate set up (i.e. connecting the output power of the generator to a sub panel) you should hire an electrician which should take a few hours or so for them to install. Let us know if you need any other assistance.

Does this come with the power connector for the electrical panel in my house.

If not could you show me the item I would need for that.


1 Answer
You would consult with an electrician to have a sub-panel installed in your home. The generator would then be connected to the sub-panel, which feeds power to select circuits on your breaker box. Thank you for your inquiry!

from Nashville, Tennessee asked:
March 11, 2019
I purchased the Earthtech Max 4800 Watt Hour Solar Generator.  We have not installed it as we are saving it for an emergency.  My question is about the batteries.  Should they be charged regularly or may we leave them in the packing containers?
1 Answer
The batteries should be installed in the Powerhub and plugged into a wall outlet or solar input, to ensure they are properly maintained. If you cannot keep them connected to a recharge source, they must be recharged every few weeks to a month in order to maintain a proper charge and ensure a full lifespan. Thank you for your inquiry!

Roger Kafer
from Columbus, Ohio asked:
September 25, 2017
How can you tell how much charge the batteries have at any particular time? Also will the unit shut down automatically if the power demand exceeds the amount of power the unit can supply?
1 Answer
When batteries are fully charged they hold 4,800 watt hours or 400 Ah at 12 volts. If you plug something in that exceeds the inverter allowance it will just simply display an error code and you would simply unplug the high drawing item and restart the unit to clear the code. Please let us know if you have any other questions.

September 17, 2017
Can I have this system tied into my whole house to power primarily my air conditioning during multi-day power outages (I live in FL, so we get multi-day power outages every few years, but solar generation is not typically an issue).
1 Answer
This unit can be tied into a backup generator sub panel and is best for all other items except for AC since AC tends to draw a lot of power compared to other appliances around the home. You would perhaps get only a few hours of run time for an AC with this system. To run AC you would need a more elaborate system such as this one: Please let us know if you have any other questions.

June 14, 2017
I realize this product is primarily used for back up power for homes, cabins and off the grid living. But is it possible to use this generator to power a dryer and an electric range inside of a house? If so what size would be recommended for the dryer and electric range if that is all that will be put on the load side of the generator?
1 Answer
Typically these products feature very large power requirements. I would recommend a larger system that features a larger maximum output. The Humless Off-Grid Series 12 kWh Generator would be a much better option: Feel free to contact us at 877-548-3387 if you have any questions regarding this system. Thank you for your inquiry!

May 30, 2017
Once hooked up is there a way to charge the batteries from my home? If so, does this reduce the life of the battery? Also, is it safe to house the solar generator in the house? Thanks
1 Answer
The Earthtech Products Max 1800 Watt Solar Generator can be plugged in directly to a 110V AC outlet for charging/trickle charging. The best way to maintain the batteries is to keep them topped off via trickle charge or above 50% power. The system is designed for use indoors and should not be kept outside (except for the solar panels and cables). Thank you for your inquiry!

Can this system be used as the ONLY power source for a 550 sq ft tiny house , and will this kit come complete with everything needed to do so
1 Answer
Great questions! Choosing a Solar Back Up Power Generator unfortunately doesn't go by square footage. To figure out if this Solar Generator would be a good fit for your application we usually ask our customers what they are looking to run. For example an energy star fridge, a fan, 4 LED Lights, etc and we can lead you to the right unit. I can tell you this kit has been used on tiny homes before and customers were pleased with the result. With any solar generator system you do have be conservative with your energy usage as to not drain the batteries down to quickly. We can guide you through this easily by asking you a few questions! It would definitely be best if you give us a call at 877-548-3387 M-F 9am-5:30pm EST. We look forward to hearing from you.
