Backup Solar System Specs:

  • Solar Panels: (2) 110 Watt panels provide 14.5% module conversion efficiency. Aluminum frame, tempered glass with EVA laminate and weatherproof film makes panels suitable for continuous outdoor use. 42.5″ L x 31.8″ W x 1.4″ H. More panels can be added.
  • Batteries: (2) 110Ah, 12V AGM (absorbed glass mat) batteries by UPG are shock-resistant and maintenance-free, producing higher cranking amps, extremely low (1–3%) self-discharge rate and greater vibration resistance. Non-hazardous, non-spillable battery design requires no water additions and rugged construction withstands harsh conditions.
  • PowerHub: 1400 Running Watts, 800 Surge Watts, by Xantrex, includes advanced technologies built in allowing people to harvest energy from multiple power sources and convert it to AC power safely and reliably. Combines an inverter/charger with battery storage compartment. Can be hardwired into a home’s AC power system, or devices can plug into 4 AC outlets. Automatic transfer switch ensures seamless transfer of electrical loads to backup batteries. Modular design allows more battery capacity to be added. 20″ L x 14″ W x 14″ H
  • Charge Controller: Stabilizes incoming voltage to prevent 12V batteries from overcharge and discharge. Digital controller reduces overall system maintenance and prolongs battery life. LCD monitor displays charging current and voltage. LED bar graph indicates battery charge level. Handles up to 30 Amps of solar array current or up to 500 Watts solar power. Maintenance free.
  • Additional Options: Even after setup, systems are exandable with additional solar panels, wind turbine or portable generator, depending on your needs
  • Incentives: 30% Tax Credit for Technology & Installation + State Incentives


Are You Looking for a Larger Solar Backup System?


The Solar Backup System above is best for emergency backup electricity, and for smaller off-grid applications such as cabins. If you would like to store and supply even more backup electricity, or you would like to outfit your entire home or building to run on solar power, check out these incredible backup solar system options!

FAQ: Frequently Answered Questions
How does a Backup Solar System work?
In one minute enough energy from the sun reaches earth to meet the entire world’s energy supply for a full year! So looking to the sun for electricity is clearly a brilliant idea.
Photovoltaic (PV) Solar Panels absorb and convert light energy into usable electricity, much as how a plant photosynthesizes. Solar panels gather energy from the sun and through the included electronics convert it into usable power!

What are the benefits of the Backup Solar System?

These systems are used mostly for supplemental and backup power, however can provide all of your energy needs depending on how much electricity you use. The benefits of these systems are many. Connected to the grid, it will sense when the power has gone out and switch to battery power. This happens automatically and instantaneously, without a break in power supply!
Batteries in the system can also be topped off from the grid, to make sure they are always fully charged. Or you can go completely off-grid for remote or mobile power, such as for a cabin, sustainable community, farm, or RV.


The included manual shows you how to connect a backup solar system. This system is designed to require only minor plug & play electrical hookup, however it is best to have an experienced electrician professionally install it for you to be safe.

What size backup solar system will provide all the energy for my house?

There are 3 components to consider when choosing a solar system:

  1. How much electricity you need at one time?
  2. How much of that electricity you want to be able to collect?
  3. How long do you need to store that amount of energy?

These 3 things figure out the size of the inverter, the number of panels, and the number of batteries respectively.

Backup-Solar-System-3Looking at your energy bill is the most accurate way to determine your energy usage. Find the average amount of KWh used per month, then divide this by 30 to see how much you use in one day. This number is used a bit later.

Next find out your required running wattage by adding up lights and appliances that you want to run at the same time, which is also used to calculate the size of your system. The average American household uses 40 KWh (kilowatt hours) of electricity each day, or 40,000 Watts, however this can vary greatly and can be drastically reduced implementing the tactics and technologies presented in saving energy at home. This includes better insulation, ceiling fans, fluorescent bulbs, solar hot water and heating, energy star appliances, digital electricity monitoring, etc.

Next, select a backup solar system with running wattage to match or exceed the total load required at any one time. Add up the running wattage necessary for those items. These systems deliver a maximum of 3600 running watts. Keep in mind that if you intend to use this as primarily a standby system, it is not likely that you will need as much power as usual, to say wash your clothes or keep your air conditioner on full blast.

Adding more panels will increase the speed that more power is delivered to the batteries, which will make more power available from the sun. Take the amount of power you want to generate in one day (KWh on montly bill divided by 30). Divide this number by the number of hours of direct sun in your location (in map below).


This is how much power you want to collect per hour. Take this number of kilowatthours and divide it by the size of the panels, such as 123 watt in this instances. The answer is how many panels work for you!Having more panels and batteries is most important in off-the-grid applications and for prolonged periods of power outage, especially where there is lower sun exposure. Keep in mind when sizing your system that some appliances or tools require temporary surge wattage at startup that can be double or triple the normal running wattage requirement.

How is the Backup Solar System regulated?

If the backup solar system is connected to the grid, it will sense when the power has gone out and switch to the solar power from the batteries. After power is restored the system will automatically transfer power draw back to the utility grid, and will resume charging the batteries. The batteries typically completely recharge in 2-8 hours of direct sunlight or grid charging. Advanced built in electronic features ensure safety, reliability, and efficiency to extend the charging capacity of your backup solar system.

Will this work anywhere in the World? (50 or 60 Hz?)

Energy is delivered at a different frequency in different parts of the world. Fortunately it is split into just two standards, 50 Hz or 60 Hz. The United States, Canada, Mexico, Japan, Philippines, Central America, Brazil, Venezuela, Columbia, Peru, and Equador are all 60 Hz. All other countries are 50 Hz. Japan has some of both standards, depending upon on the location.

The Backup Solar System at the top of this page is 60 Hz only, however the larger backup solar systems are available in 50 Hz options.
