1410W solarChoose the off-grid battery option that best fits your off-grid application. The size of the battery bank depends on the amount of power you require (Watts), the amount of time each day you expect to run your appliances, equipment and lights, and your location or available sunlight (If you are adding solar or wind power). As a rule-of-thumb, when considering batteries off-grid, use 3 days of autonomy (No Sun) as a minimum and 50% depth of discharge for your battery bank (80% Maximum).

**Freight Shipping (Freight Delivery is Dock to Commercial Dock)

solar kits

Item that are too large or heavy to ship UPS and have to be palletized are shipped by ground freight. In circumstances where we offer shipping, free or otherwise, that means dock to commercial dock (not residential) to any of the lower 48 states. If the customer does not specify a local commercial dock that is available, we will ship to the nearest terminal where the shipment will be held for will call pick up by the customer. If you choose to have your order shipped to your residence, most orders require special handling for unloading and the pallet has to be transferred to a truck with a lift gate. In most cases, truck freight companies do NOT require their drivers to unload shipments. An additional "Residential" as well as a "Lift Gate" special handling fee will apply if the driver unloads the merchandise to the curb at your residence. The special handling fee is $89.00 and is available at checkout. If you have selected this add on service, the shipping carrier will call and schedule delivery of your solar kit, (provided the weight and dimensions of the product fits the criteria for lift gate service). You can avoid the residential and lift gate fees by arranging a "Will Call" pickup at the closest freight company terminal. In that case, you will need a pickup truck, a copy of the bill of laden, and a photo ID. When you arrive at the freight company terminal, the freight company will load your order into the bed of the truck with their forklift. The most common pallet size = 65" X 44" (Height depends on Product). Be sure and check for hidden damage.

Off-Grid System Sizing Starts With a List of Equipment

The size of an off-grid solar electric system depends on the amount of power that is required (watts), the amount of time it is used (hours) and the amount of energy available from the sun in your area (sun-hours per day). A homeowner has control of the first two variables, while the third depends on location. We know we are preaching to the choir when we say conservation plays an important role in keeping down the cost of any solar system, but it plays a much bigger role in off-grid solar. To start the off-grid design process, we recommend you make a list of your lighting, refrigeration, major and small appliances and well as estimate in each case how long you usually use each one each day (Duty Hours). (Don't forget well pump if you intend to run it off the same set of batteries). Standard freezers and refrigerators can use 3000 watt hours each day. A few better models like Maytag MTB1956 18 cu ft can be found to use under 1500 watt hours a day, and cost around $900. Refrigeration cycle time is usually a function of efficiency, but also it is a function of how full the unit is, how often it is opened, and the outside temperature. Typically we use 10 hours as the duty hours for most refrigeration calculations. To illustrate the point, the daily energy use of a R10 high efficiency SunFrost refrigerator will use 13 amp-hours (170 watts) at 70 degrees, but 23 amp-hours (280 watts) at 90 degrees.

When considering the battery capacity needed, first look to more energy efficient appliances. Then we suggest you consider battery capacity (kWh or Ah) to be a minimum of twice the average daily solar electricity generation. For longest life, sealed maintenance-free batteries (VRLA, gelled electrolyte, AGM, etc.) should not be discharged to greater than 50% of their total capacity rating within a 24 hour period.

Minimum suggested battery capacity (kWh or Ah) is the largest battery bank size that the solar arraay can recharge from 50% depth-of-discharge (DOD) on an average day in December. When we design an off-grid or bimodal solar system when calculating battery capacity (kWh or Ah), we assume there is no other means of recharging the battery bank other than the solar system.

Here are some average home appliance wattages to help you get started on your list:

 
Laptop 50 - 65 Watts
Cell Phone 5 Watts
Table lamp 25 Watts
Inkjet Printer 50 - 75 Watts
Clock Radio 10 Watts

500 Watt solar nec500 Watt building code compliance

NOTE, IMPORTANT 500 Watt Off Grid Solar Kit INSTALLATION: (OK, here is the scary legal disclaimer.) It is the responsibility of the purchaser to ensure that all products are installed and operated in accordance with local and national building codes as specific by the NEC (National Electric Code), UBC (Uniform Building Code) or IBC (International Building Code) and local utility company policy. These codes may vary from city to city and county to county. All off-grid solar installations should be permitted and inspected, where required, by  the local inspection authority in the same manner as other equivalent electrical systems. One last thing. It is always a good idea to contract with a local licensed electrician to at least do the final electrical connection of your 500 Watt Off Grid Solar Kit from the AC disconnect to your home utility breaker box. Some local permitting authorities require that a licensed electrician do all the wiring from the rack to the utility interconnect. If you need help with the permitting documents for your 500 Watt Off Grid Solar Kit package, we are here for you. Solar permit service add on is available at checkout.
