System Description 

This system is a grid-tie, PV system with battery back up, with PV generation consisting of 42 Solar World 

SW-240 modules with a combined STC rated dc output power of 10,080 watts. The modules are 

connected into two groups of five 3-module source circuits and one group of four 3-module source 

circuits that feed three Outback FM80 charge controllers. The charge controllers feed the system batteries 

and the inverters, which are connected to supply 120/208 volt ac (uninterruptable) to the standby loads 

and also to the electric utility grid. The system is provided with all disconnects and labels required by the 

National Electrical Code. The system batteries are sized for 610 amp hours at 48V providing approximately 

27.0 kWh to standby (uninterruptible) loads.

Interruptible 

Loads 

When the sun is shining, power from the PV array is used to keep the batteries fully charged. After 

charging the batteries, the PV power is made available to the standby loads. If the PV power meets the 

requirements of the standby loads, any remaining PV power is then directed to the interruptible loads of 

the occupancy. If any PV power remains after the interruptible loads have been powered, it is delivered to 

the utility. When utility power is available, but PV power is not available, standby loads are supplied by 

the utility. If neither utility nor PV power is available, standby loads are supplied by the batteries. Thus, 

the batteries are only cycled if utility power is lost. The batteries used are specially designed, deep cycle, 

maintenance free batteries that are capable of undergoing approximately 3,000-4,000 charge-discharge 

cycles. Designing the system to minimize battery cycling extends the life of the batteries. 

The inverter meets the requirements of IEEE 1547 and UL 1741. This means that if it detects a loss 

of utility power, it will automatically disconnect from the utility. When this happens, only the 

uninterruptible loads are powered by the inverter. When utility voltage is restored, the inverter 

automatically reconnects to the utility grid after verifying the utility voltage and frequency stability. 

On a average day of Florida sunshine, the system will produce approximately 36.5kWh of clean 

energy.

approximations. Minor Adjustments left to the discretion of the 

Contractor may be necessary pending the identification of any 

underground utilities and unforeseen obstructions. 

2. A double barrier fence no less than 10 ft apart is required around the 

perimeter of the construction site during construction. 

3. The location of all underground utilities must be performed by the 

contractor prior to any construction. 

4. Final Array Fencing must be spaced 11' Min from East West and South 

sides of Array for a 6ft fence and a 3' Min for a 4ft high fence.

Battery Backup Grid-Connected Photovoltaic Emergency Power System Installation Notes 

The following is a brief summary of equipment installation notes. The owner and the installer will be provided 

with all manufacturers' instruction manuals as well as a copy of the materials that have been submitted to the Florida Solar 

Energy Center for design review of the system. 

Summary of Major Equipment Manufacturer, Model and Listing/Compliance 

Note that the Outback GVFX3648 Inverters will supply a maximum of 10,800 watts if the utility grid is down. When the 

utility grid is up, the three inverters will pass through 50A @ 120V, or 18,000 VA. If the utility grid is down, the system 

operates as a stand-alone PV system and is thus subject to the provisions of NEC 690.10(A). When the utility grid is 

operational, the PV system loads are subject to NEC 220. 

Note also that the PV system can be expected to generate approximately 36 kWh per day as long as the day is mostly 

sunny. In the event of a utility outage, run times of loads may need to be adjusted on a daily basis to avoid having the 

inverter shut down if the battery state of charge reaches the minimum allowable limit of 44 volts. 

When the utility is in operation, the kWh consumption is no longer limited by battery capacity, since the grid will supply 

14,400 VA continuously (50A C.B.) via the inverter if necessary.

A. Electrical Notes 

1. Modules are prewired with #12 PV Wire conductors with molded W/P connectors. Use only the connectors 

provided for connecting modules in series. Do not cut connectors off as this may void the manufacturer's 

warranty. Do not disconnect connectors under load. 

2. Module output is DC. Twist-on connectors are not suitable for use with DC. Use only the terminal strips or 

Polaris taps enclosed in a weatherproof junction box to transition wires if needed. 

3. If junction boxes are used, use cord connector strain relief at junction box entries of module open wiring 

conductors. Be sure connectors are tightened sufficiently to prevent water entry into the junction box along the 

wires. 

4. Use lay-in ground lugs or WEEB components for grounding modules and module racking. Mount ground lugs to 

modules using #10-32 self-threading stainless steel bolts, nuts and lockwashers that are provided with the lugs. 

Use #10 solid bare wire in continuous runs to ground modules. Removal of any module from the system must not 

affect the grounding of the remaining modules. 

5. Bond all array mounting structure to modules using approved bonding clips. Use one clip for each individual 

length of mounting rail. 

6. Strap all module open wiring neatly to the mounting frame using UV resistant wire straps. 

7. Follow school building code requirements for all electrical conduit and and components. 

8. If DC wiring passes through building interior space, NEC690.31(E) requires that the wiring be enclosed in 

metallic conduit up to the first readily accessible disconnecting means. 

B. Mechanical Notes 

1. Use Stainless Steel hardware to attach PV Modules to PV Array mounting frame 

2. Follow module mounting detail shown in mechanical drawings of mounting frame. 

II. Source Circuit Combiner Box Installation 

Follow manufacturer's instructions. 

III. FW1000 AC and DC Disconnect Enclosure Installation 

Follow manufacturer's instructions. 

IV. System Batteries Installation 

Follow manufacturer's instructions and install in accordance with NEC requirements. Maintenance free 

batteries will only need to be vented at the top and bottom of battery container to keep the batteries cool, as per 

IEEE 1187 and the terminals will need to be protected from accidental short circuits. 

Use only UL listed cables and cable lugs crimped with approved UL crimping tool. The use of fine stranded 

battery cables is highly recommended to reduce the strain on battery terminals. Do not use battery lugs that have an 

inspection peep hole for battery connections, as these lugs are not suitable for use with batteries. 

V. GVFX 3648 Inverter Installation 

Follow manufacturer's instructions for installation and programming via the MATE system controller. 

VI. MX-80 MPPT Charge Controller Installation 

Follow manufacturer's instructions for installation and programming via the MATE system controller. 

VII. Balance of System (BOS) Component Installation 

The balance of system components are shown on the electrical schematic diagram. These are standard AC 

components that require wiring according to NEC, using standard wiring practices. In particular, the point of 

utility connection (PUC) has been designed to meet the requirements of NEC 690.64.
