Frequently Asked Questions
     
  How do I properly charge a deep-cycle battery?  
  Deep cycle batteries must be charged according to their capacity (amp hours). Please refer to your manufacturer’s instructions for individual instructions.  
     
  How do I properly discharge a deep-cycle battery?  
  All deep cycle batteries vary in depth of discharge rates. It is not good for any deep cycle battery to be discharged more than 50% on a regular basis. As in charging deep cycle batteries, the manufacturer specifications should be consulted for accuracy.  
     
  What is a battery bank?  
  A battery bank is the primary means to store your energy for future use.  
     
  How do I know what size a battery bank I need?  
  Battery banks must be sized to your estimated usage. Through many years of experience, we estimate a conservative household with one or two occupants with a 4000watt inverter should have a minimum of 1600amp hours at 24v DC. Due to the complexity of sizing accurately, please contact us for more information.  
     
  How do I know what size an inverter I need?  
  To determine this, the maximum amount of energy needed to run your electrical appliances (microwave, washer, television, lights, etc.) at the same time is calculated in terms of wattage. Every inverter is sized according to wattage – it is better to go over than not have enough watts.  
     
  How do I know when to run my generator?  
  Our primary line of inverters will automatically start your generator when needed. Or, you can manually monitor your solar system with an “e-meter” or amp hour meter (fuel gauge), this tells you how much energy is still left in your batteries and will help you determine if running a generator is needed.

  How do I whether I need 12v or 24v?  
  Most 12v systems are mainly designed for recreational vehicles and small cabins and homes. 12v is not recommended for larger systems and needs. Your system will be more efficient if the input voltage is close to the output voltage. Because of individual requirements, it is best to have each system properly sized.  
     
  Do all systems need to be housed separately or can I put the system in my garage?  
  Inverters are best installed at the closest possible point of its power source (i.e. batteries). It is more efficient to “push line than supply voltage”. Batteries are not recommended housed in a garage setting because of ignition sources and explosive gases. Generators are usually housed separately strictly for noise and emission protection. Therefore, all Abney Electrix systems are designed away from living areas for safety and noise control.  
     
  What types of inverters are available and what are their differences?  
 

There are three basic types: square wave, modified sine wave and true sine wave.

  • Square wave inverters are mostly obsolete and are not recommended due to their inefficiency, harshness for ac appliances, and noise.
  • Modified sine wave inverters are the most popular inverter. This type of inverter is used in most recreational vehicles and off-grid systems. For most electronic devices, these work well. They are not, however, recommended for highly sensitive electronics and ac motors (fans and pumps).
  • True sine wave inverters are best for sensitive electronics, and ac motors (fans and pumps). The output wave pattern of a true sine wave is virtually the equivalent to 60hz grid power.
