Battery Backup Solar Systems

Battery Back-Up

  • Home owners and businesses today are considering adding battery power. During an outage, our "battery-backup" systems automatically disconnect from the grid and power your home with standby battery power.
  • Battery back-up is a modest system, perfect for people who are powered from the grid (the utility) but want to be prepared for power outages. You may choose a small system to back-up the most important appliances that need electricity at all times. Back-up systems are different from Off-grid systems; which are for people with no utility service.

Off-grid Solar Systems


  • An Off-grid system is a more robust battery system, designed to power your entire home year after year.
  • An Off-grid system can prevent having to pay thousands in initial wiring foundation costs that has for some of our clients surpassed the costs of an entire solar system.
  • Batteries for off grid is to avoid a house from having to be grid tied; but can also be used to offset demand charges and high electricity charges at specific times of the day.


String Inverters VS Micro-Inverters

Our experts have found that the right selection of inverter combined with the right solar panels proves to be the most important feature of a solar system design.

  • Inverters: All solar panels generate DC (direct current) that needs to be converted to AC (alternating current) for use in homes and businesses. The main function of an inverter is to convert the solar panel current from DC to AC.
  • Some companies use a large string inverter that is installed in a home garage or basement. Other companies use micro-inverters that are installed under each solar panel. Our experts have found installing micro-inverters on each panel not only increases failure points but they also have high failure ratings due to being exposed to harsh weather conditions.

  • Optimizers: On solar systems designed using a string-inverter, optimizers were once needed to be installed under each solar panel as a solution to the power production loss of all panels due to just one panel's exposure to partial shading. Optimizers on each panel not only increases failure points but they also have high failure ratings due to being exposed to harsh weather conditions. Our high-tech Solaria panels have substring technology for optimization; therefore in our solar system designs the need to install micro-inverters or optimizers has become obsolete.

Solark Vs Tesla's Powerwall

Tesla’s Lithium Cobalt batteries are just not there yet when it comes to safe long lasting technology. The continuous power output of a Tesla EMS (Energy Management System) is 5 kW vs our 8 kw Sol-Ark system.

  • To double the continuous power, another entire Tesla EMS would need to be purchased; as opposed to adding one extra inverter to double the continuous power output of Hudson River Renewables battery systems. (Link to Sol-Ark Inverter technical details)
  • Our Sol-Ark batteries cost less and are much more durable and last just as long. Our Sol-Ark lead-carbon batteries last as long as the Tesla lithium cobalt batteries. Sol-Ark batteries are tried and tested to charge in sub-zero conditions with no need to store in heated spaces near or inside of your home. (Link to Sol-Ark battery technical details)

At Hudson River Solar a battery system can be designed to power an entire home off-grid, but may also be sized much smaller for just those few important appliances needing power during a power outage. Businesses use batteries to benefit from offsetting demand charges and keeping security lights and machinery on during outages. We can add batteries to an existing solar system or quote a solar array to perfectly accompany your battery backup or off-grid battery storage system.
