Greenhouse Office - Assignment Example The parallel and series connections have to be checked. It was stated that the batteries were fully charged but now the SG is low. The back-up generator should do the charging in this particular case because the PV array may not be able to give the required electricity generation. The solar array should also be checked for possible defects. An inspection on the conduit and wiring associated with the array and the two regulators should be done, finding some possible breaks or deterioration on exposed conduit and wiring. If there are leaks or open wires, conduit and wiring should immediately be replaced or repaired if possible. Suppose however, that we can't find fault in the PV array and the wiring and conduit are all in normal and good condition. What do we do That fuses blow up is probably because of the overload, meaning it can not give the necessary power to its load, the appliances and lighting in the house. A point from the generator and the array towards the battery charger and the regulators should be checked. There must be some leak here that prevents the battery bank from charging. As we can see in our diagram, the energy generating phase goes to the energy storage phase or equipment composed of the batteries, their housing and any protection equipment. The systems should use batteries which are designed for deep cycling applications and which are better suited to the charging and discharging regime typical of RAPS systems. There are two regulators each fed by half of the PV array. Can we point to the regulator as the possible 'culprit' Or, possibly it can be one of the 'culprits', meaning we have here one or two faults or defects. A regulator is an electronic device which controls the voltage of the solar array's energy output to charge the battery bank appropriately. An inspection is necessary on the functioning of the regulator to ensure that indicators or meters are correctly operating for the various regulator modes. When the batteries are fully charged, the regulator should be in the float mode. The regulators are connected to the battery charging equipment so that over voltage is not delivered to the battery. But the low SG in the batteries indicates that the charging equipment does not deliver the required power to be charged to the battery bank. The batteries can not work or can not have power without the charger, so this has to be in good working condition all the time. An old battery charger can cause trouble such as brownouts if it fails to charge the batteries which in turn supply the inverter. The components in the circuit of the charging equipment also consist of heat-sinks. Overheating in the heat-sinks and components should be checked. There could be some damage in the charger. The battery charger's performance worsened during bad weather where leaks and open wires could expose the system to short circuit and malfunctioning. Another trouble could be pinpointed at the wiring connection between the regulator and the charger, but a thorough checking revealed that there was no leak, neither was there open wire, nor
