DISASTER PREPAREDNESS

Solar energy can be used for anything from a trickle battery charger to a whole house system. Our small 5 watt and 30 watt solar panels are 5 to 6 volt, and our 60 watt panels are 12 volt. We use only 60 watt panels as they are easy to ship via UPS and because we get volume prices on purchasing only one size. Only a small 5 watt system will only need just the solar panel without batteries or a solar controller. Batteries are required so power can be provided when the sun is not shinning. All but the 5 watt system will require a solar controller to keep the batteries from over charging as the solar panels will overcharge and damage batteries. An inverter must be used to power 120 volt or 240 volt house voltage. The inverter converts 12, 24, or 48 volts DC voltage to 120 or 240 volts AC voltage. Only very large systems over 3,000 watts will use a 240 volt inverter to power both 240 and 120 volt loads. Keep in mind that a 12 volt current is always 10 times the current at 120 volts and that the proper size wires must be used to handle the high 12 volt current. Using 24 or 48 volts will require smaller battery and inverter input wires and is best for larger systems. At least a 960 watt system with at least a 3,000 watt inverter will be required to provide 50% to 80% of the 120 volt power for a house. The 3,000 watt inverter will need to be supplied with wire capable of supplying about 300 amps if using 12 volts, and if using 24 volts the wire will only need to supply 150 amps. The proper solar controller with the proper relays and batteries capable of supplying the high current will also be needed. Our deluxe solar controller is capable of automatically changing the the power source from solar or house power as needed with the proper wiring of loads you want powered with solar. There is more information on solar controllers, inverters, and batteries below. Make sure you read our entire page below before ordering. Before installing a solar system you should take every step possible to use less power such as replacing all light bulbs with florescent or LED bulbs. These bulbs are available below. Tax credits may be available in your area for installing solar systems. The federal tax credit has many restrictions and must be an on grid system which is very expensive and in most cases is not worth the extra cost. Contact your government agencies to see what tax credits may be available in your area. To help you to select the proper system for your needs see the table below.

We manufacture our own Solar Controllers which are all Micro Controller controlled and provide many features not found on any other controllers. All our controllers come with heavy duty steel enclosures with multiple knockouts. They are all for indoor use only, can be instaled on 12, 24 or 48 volt DC systems using 6 or 12 volt batteries. The wattage or current should not be exceeded so make sure you order the proper controller for the wattage of your solar panels. For example, a 960 watt system of solar panels that is wired 24 volts will only require 40 amps but because it is a 960 watt system you should use the model SCD2 controller as the model SCD is only rated for 480 watts. Our basic controller is a low cost controller for systems up to 140 Watts or 10 amps. It has indicator lights to indicate the battery voltage, low battery warning, and solar charge off when the batteries are fully charged. Our deluxe controllers have indicator lights to indicate, battery voltage, night, and solar power off. They also have a circuit to automatically disconnect the solar power and connect the house grid power to the AC load if the battery voltage is low and then automatically connect the solar power and disconnect the house grid power when the batteries are partially charged again. An optional relay is required for this option. This system prevents the batteries from excessive discharging, which shortens the life of the batteries, and also protects the inverter from low voltage and shutting off and not coming back on and other low voltage problems. Some inverters shut off and do not come back on until they are manually reset when the input voltage is below 11 volts, and some inverters will turn off and on when the voltage is low which may damage some AC loads.

An inverter must be used to power 120 volt or 240 volt house loads. The inverter converts the 12, 24, or 48 volt DC voltage to 120 or 240 volt AC voltage. Only very large systems over 3,000 watts will use a 240 volt inverter to power both 240 and 120 volt loads. Keep in mind that a 12 volt current is always 10 times the current at 120 volts and that the proper size wires must be used to handle the high 12 volt current. Using 24 or 48 volts will require smaller battery and inverter input wires and is best for larger systems. At least a 960 watt system with at least a 3,000 watt inverter will be required to provide 50% to 80% of the 120 volt power for a house. The 3,000 watt inverter will need to be supplied with wire capable of supplying about 300 amps if using 12 volts, and if using 24 volts the wire will only need to supply 150 amps. The inverter typically has 2 to 4 times the power capability of the solar panels so that it can supply power to higher power loads as needed such as a refrigerator, washer, or kitchen appliances. The solar current is the charging current only and is the solar watts divided by the system voltage.

There are two types of inverters. Most inverters are low cost modified sign wave and are what you should use in most cases. These are off grid inverters which are not connected to your house power. Any AC loads must be connected only to the solar power or house power but not both at the same time. True sign wave inverters are more expensive and may be off grid or on grid inverters. An on grid system is required along with many other restrictions to get the federal and some other tax credits. Contact your government agencies to see what tax credits may be available in your area. We are a delaer for AIMS POWER and we have inverters for every application including RV, auto, construction, and solar.

The batteries must be capable of storing and supplying the proper power to the inverter. You will need to use 12 volt batteries or two 6 volt batteries in series to get 12 volts, or four 6 volt or two 12 volt to get 24 volts, or eight 6 volt or four 12 volt to get 48 volts. The number of batteries needed depends on the size of the solar system, inverter, and load desired to supply. Sams Club and Costco have 6 volt Golf Cart batteries in most areas that are a very good battery for solar storage and are the battery we recommend. Batteries are costly and a battery life saver (BLS) should be used on all batteries. Every home should not be without one. See Below.

Battery Life Saver (BLS)

What is The Battery Life Saver electronic device?

The BLS is a patented electronic device that brings old and weak batteries back to life, restores functioning batteries to a like new condition, and extends battery life by keeping batteries from losing capacity and life due to the main cause of battery failure which is the buildup of lead sulfate on the battery plates.

Why is The Battery Life Saver electronic device needed?

75% to 80% of lead acid batteries fail prematurely because of formation of lead sulfate on the plates. These crystals cause batteries to become unusable at approximately one-third of their natural life. The Battery Life Saver electronic device dissolves the lead sulfate crystals.

How Does it Work?

Using breakthrough square wave technology, The Battery Life Saver electronic device sends a frequency signal to each crystal of lead sulfate, causing it to dissolve into lead and sulfuric acid. This restores the battery to its original condition and allows the electrical charge to be drawn from the battery.

Benefits of Using The Battery Life Saver electronic device.

It makes old batteries as good as new. It keeps new batteries like new, saving time and money. With The Battery Life Saver electronic device, more power is available from your battery and you need less power to charge it. By reducing the number of batteries that get thrown away and put in landfills, the Battery Life Saver electronic device protects the environment.

The Battery Life Saver electronic device Can be Used in Several Different Ways:

Connecting and using the Battery Life Saver is very easy, just connect it and forget it! Only one device is needed per battery system. The device works off of the power of the battery (the system should be charged regularly), and therefore does not have to be plugged into AC power. All of the units come with two leads(wires) just like jumper cables. Simply connect the red wire to the main positive battery terminal and the black wire to the main negative battery terminal. Some units are equipped with alligator type clips and others come with eye rings for permanent attachment to the batteries.

• To restore a dead or barely usable battery, connect the Battery Life Saver electronic device to the battery, along with your battery charger. The Battery Life Saver will gradually rejuvenate the battery or battery system with every cycle(charge and discharge). With the Battery Life Saver connected, fully charge the battery, then discharge the battery (the BLS operates from the power of the battery, thus you can use the BLS to discharge the battery). This process can take a couple cycles or many cycles depending on the condition and size of the battery or battery system.

• To maximize battery life, connect the Battery Life Saver electronic device to your new battery or battery system and let it be!

• To maintain working batteries, install the Battery Life Saver electronic device on your battery or on a bank of batteries. It rejuvenates the batteries while it is in service. This causes more power to be available from the battery and causes less power to be needed to charge the battery. This is the best way to extend the life of your batteries. It’s like having a brand new battery every time you use it.

We are stocking the models below but we have many different models available for different types and voltages of battery systems including 12, 24, 36, 42, 72, 84, 96, 120, 144, and 156 volt DC systems. Call or email for more information on the other models. Please provide the voltage and application when contacting us.

For 12 and 24 volt battery systems. Also ideal for use with a battery charger to rejuvenate unusable batteries. Comes with alligator type battery clips for attachment. This is the best BLS model to rejuvenate old batteries. Comes with two 3/8" eye rings.

The wires from battery to battery and to the inverter must be large enough to supply the proper current to the inverter and are usually much larger than the wires from the solar panels to the controller and batteries as these wires only carry the charging current. On larger systems it may be easier and more cost effective to use multiple wires in parallel instead of one large wire. For example, if you need 120 amps you can use four #10 wires instead of one #2 wire. Using multiple wires to the solar panels and batteries allows you to wire the them in groups of 4 to 12 depending on the voltage and wire size. Always locate the batteries, solar controler, and inverter as close as possible and within just a few feet. Before purchasing wire you need to know which inverter you are using and the DC and AC current and voltage. Using a higher DC voltage saves money on wire as the current is lower, but on smaller systems it is best to use 12 volts. A 24 volt system uses half the current of the 12 volt system and a 48 volt system uses half the current of a 24 volt system. The batteries and solar panels are wired in series to get the desired voltage. For example, if you want a 24 volt system four 6 volt batteries or two 12 volt solar panels in series will create a 24 volt system. These will be connected in parallel to others as needed for higher capacities. You can purchase wire at your local electrical supply or hardware store. Check the current rating of the wire before you purchase.
