3. UM S LAR SOLAR ELECTRIC MODULE ES 124 amp ES 62T Owners Manual and Installation Guide CAUTIONS Solar electric modules produce DC electricity when exposed to light The voltage from one individual module is not considered hazardous However if modules are connected in series to increase voltage or in parallel to increase current the shock hazard increases When installing or working around photovoltaic modules batteries and related electrical equipment AA4 3699 01 observe industry standards and practices as well as manufacturer s safety recommendations WARNINGS Cover the solar modules with an opaque material before making your wiring connections This will prevent the modules from producing electricity while making the connections and reduce the risk of electrical shock or sparks Use insulated tools and observe safe electrical practices at all times Make connections in a well ventilated area free from flammable gas vapors and open flames Observe proper polarity when connecting the modules into an electrical circuit Reverse connection will damage the module and may result in fire Do not use any solar module without a blocking diode to prevent reverse currents from flowing into the module from the battery A charge controller with a blocking diode or night time disconnect feature will work well in this capacity Do not attempt to concentrate sunlight on the
4. ing source ex a generator All systems that include a battery must have a blocking diode between the battery and the solar module Usually the blocking diode or night time disconnect circuit is included with a charge controller i e voltage regulator Additional series blocking diodes can be used within the array one diode per parallel string to increase daily array output in locations with severe shading over parts of the array during peak sun hours 09 30 to 16 30 United Solar Ovonic requires the use of a properly sized fuse on single modules or strings of modules wired in parallel with other strings of modules or individual modules See table for appropriate series fuse rating Bypass Diodes Every solar module includes a bypass diode across each cell which results in reduced power loss under partial shadow conditions When two 2 or more modules are connected in series a bypass diode can be installed in the module junction box using the supplied jumpers providing further shadow tolerance For assistance contact United Solar Ovonic Charge Regulation The use of a charge controller i e voltage regulator is recommended in battery systems to prevent the solar module from overcharging the battery and to optimize the charge rate for the battery Follow the manufacturer s instructions for installation of the charge controller High Voltage Systems Solar modules are suitable for use i
