SOLAR PA USER MANUAL Solar PAs provides a battery operated public address system with additional power for running a projector and other small electric devices Included are solar panels for recharging the battery It will provide dependable power anywhere the sun shines GENERAL CONSIDERATIONS Solar PA s have created a fully integrated system that works well The 120 watts generated by solar panels in a sunny climate will be able to recharge a 60 amp hour battery in 1 day the 400 watt inverter will run the recommended projector DVD player laptop or other accessories Wherever possible 12 volt DC equipment is used to eliminate the need for additional inverter capacity and to avoid the inefficiencies of converting voltages up and down Inverter size batteries and solar panels can be adjusted to meet power needs when they are known The standard unit comes set up for one battery Capacity Books on solar power talk about power needs and how to size your solar system to do what you want This unit is sized for heavy use such as showing movies using both a projector and the PA system for 2 to 3 hours a day or for limited use just the PA system as well as charging some cell phones or other batteries for up to 8 hours a day Asmall laptop may be able to run 12 hours a day if that is all that the unit is used for With 2 or more batteries you may be able to use the system longer one day but the 120 watt solar panels will need two or three da
3. case and to the Y Once the cord is all plugged in the green charge light on the charge controller should come on The charge controller won t activate if the battery voltage is below 11 volts When the battery is completely discharged bypass the controller to start the charging If the green light doesn t come on and the controller indicates 11 volts or greater you will need to make sure the panels are in full sun and the connections are goad Consider changing the direction the panels are pointed every hour or two so they remain close to perpendicular to the sun s rays especially if the battery is discharged or you are using a lot of power during the day Since the glass surface of the panels gets very hot you should elevate the panels not only to protect them from being stepped on and broken by animals but also to protect bystanders from being burned by them A 40 10 metre cord is provided so the panels may be placed on a roof where they can get full sun and be protected from damage When the battery is fully charged the charge controller will stop charging the battery When using less electricity than the panels are providing the controller cycles on and off This is normal Voltage on a 12 volt battery varies as the charge condition changes Each battery is slightly different The specifications on the battery used for testing the system are as follows 12 84 volts or higher the battery is 100 charged 12 60 volts th
4. e battery has 75 of full charge 12 18 volts the battery is 50 charged 11 88 volts the battery has 25 of a full charge The inverter shuts down when the voltage is at 11 volts or less When using the system check the voltage on the digital readout of the charge controller so you know the condition of your battery Your battery may vary somewhat from the chart above but after a few days of use you should get an idea for how it performs Ask your supplier for a chart for your battery Plan your activities so they end before the battery quits and the systems in use shut down SOLAR PA USER MANUAL BASICS OF THE ELECTRICAL SYSTEM A six fuse panel mounted inside the case protects the equipment and the battery The positive pole on the battery goes to the fuse panel the negative goes to the connector bar on the other side of the amplifier current fuses are as follows 30 amps for the PA amplifier 30 amps for the inverter 20 amp for the 12 volt power outlet 20 amp for the solar panel incoming power 15 amp for the mixer board 15 amps for the lights All fuses are type ATC Using the sound system On the control board the switch on the right turns on the main amplifier the switch on the left turns on the mixer Connect all the equipment microphones instruments DVD players etc turn on the mixer and then turn on the main amplifier Using the lights There are 2 small sockets type M female on the board and one on each lig
5. ht 2 cords with male plugs are provided Turn lights on by plugging them in There is a hole in the base of the lights which will fit on a microphone stand Using the inverter A 115 volt 400 watt inverter is included This will run the optional projector and other small items Most laptop computers cell phones and battery chargers will run on this Check the labels if watts aren t listed multiply volts x amps to get watts Add together the watts of each item you will be plugging in The maximum total load on the inverter is 400 watts The inverter draws power whenever it is turned on even if nothing is plugged into it There is a switch on the inverter to turn it off when not in use and avoid draining the battery Issues if using multiple batteries If you are using 2 or more batteries it is important to insure you get equal draw from each battery This means you need to wire the batteries in a way to insure there is equal resistance in the wires from each battery to the load The simplest way to do this is as shown With the wire to the load from one battery and the wire to the load coming from the other battery SOLAR PA USER MANUAL SOUND SYSTEM The MX 153 comes with 2 microphone inputs SLR and 3 stereo line inputs RCA and 1stereo line out RCA The 3 line input also has an 1 8 stereo jack on the front of the board for connecting an mp3 player Any mixer board using less than 400 watts could be plugged into the
6. inverter and the power amplifier and used in place of the provided mixer Two microphones are provided if you need additional microphones wireless microphone receivers could be plugged into the other inputs You could also use the additional inputs for a DVD player an mp3 player an iPod a key board or any other instrument with a line out jack The line out on the mixer goes into the line in on the amplifier The amplifier output goes to the two 1 4 phone jacks on the main board Two 25 7 5 metre cords are provided for the speakers The amplifier Crunch GPV 700 2 is a 700 watt 350 watts at 4ohms peak power amplifier It is designed for 2 to 4 ohms of resistance from the speakers Speakers provided are 4 ohm The KS 69 can handle a peak power of 270 watts compared to the amplifiers output of 175 watts per channel The speakers are sized for the amplifier however a high input level could overload and burn out the speakers Order of setup for use Connect power cord to mixer connect mixer to main amplifier Plug in speakers microphones mp3 players etc Turn all volume controls to 0 Turn on mixer Turn on amplifier Slowly turn up volume to desired level K Use and enjoy LIGHTS Order of setup for use 2lights and two cords are provided Plug cord into panel and light Unplug when done using as no switch is provided connection of mixer to main amplifier light which will fit on top of a microphone stand This will
7. ys to fully recharge them It is also possible to use a generator car or other charger to recharge the batteries No hookup is currently provided but it is simple to open the case and clip cables onto the battery terminals Battery Type and Usage A deep discharge battery is essential for normal use of the system Lead acid batteries will last longer when not discharged below 50 of their capacity so two batteries discharged to 50 each night could last up to several years while a single battery discharged 100 each night would only last afew months A sealed battery is o gt recommended as the unit is often tipped when it is being transported A standard gt ae battery will leak especially if the unit is left on its side which will ruin the battery and much more Sealed batteries aren t always available if you get a battery which isn t sealed be especially careful that the unit isn t tipped on its side for extended periods The 8 acid is very corrosive d a f y When using the PA system the lid needs to be open so the amplifier and inverter don t overheat SOLAR PA USER MANUAL Control panel CHARGING THE SYSTEM The panels have newer crystals which will do limited charging on bright cloudy days but will work best in full sunlight and aimed directly at the sun The panels should be at a 90 degree angle to the sun s rays Each panel has its own connection hook each panel to the Y then hook the cord to the
