Frequent Questions: Misc.

How will your systems handle in the event of an EMP? 
An EMP (Electro Magnetic Pulse) can be the result of a solar flare or nuclear blast.  Coils, long runs of cables and microelectronics are especially susceptible to the damaging effects of an EMP. Solar panels would most likely be able to survive anything that your DNA can survive because solar panels are essentially just flat sheets of silicon.  Charge controllers, converters and inverters, on the other hand, would not fare as well because they contain coils and microelectronics.  One way to protect these components would be to enclose them in a grounded Faraday cage, which is basically a metal box with a cable going to a grounding rod.  Considering how impractical this would be in an RV, and all the bigger problems you would have with every other system being destroyed in your RV (and the world around you for that matter), we recommend just avoiding EMPs.

How much lithium battery capacity do I need to run an air conditioner? 
As a rule of thumb we recommend 200Ah of lithium batteries for every hour of run time for a standard RV air conditioner.

I’m living on a fixed budget and I want to get rid of my energy bill.  Is solar a good option? 
Most of our customers buy solar equipment because it gives them the freedom to camp without shore power or to reduce the amount of time that they have to run a generator, not because it is cheaper than the utility company.  That being said, if you are a full time RVer, and the system we install dramatically reduces the number of times per year you have to pay for a full hookup, you could see a shorter payback period with your RV system than you would with a residential solar system, only because full hookup camp sites charge you for a lot more than the value of the utility power you consume.  An RV power system will cost between $5,000 (really roughing it) to about $25,000 (most of the comforts of home), and that amount of money could pay for a lot of energy bills.
