pit SYSTEMS Proposal Date: Dec 007, 2018 No: A-0650 ProSolar America, LIc. 4011 New Herrnhut St. Thomas, USVI, 00802 340 201 4752 Great Saint James Storage Retrofit Prosolar is pleased to submit our Lump Sum Proposal to furnish all labor, consumables, equipment, tools, supervision, testing, and engineering to perform the following referenced work: Our recommendation, based on the final testing of the individual stacks is to replace the 310kWh battery bank with a 305kWh lithium-ion solution. Our recommendation is based on a few key elements: 1) Equivalent battery capacity 2) Plug-and-play compatibility with your existing system 3) Increased kVa output to better manage large loads 4) Better online communication 5) Increased integrated battery management system 6) Sound vendor balance sheet to ensure warranty accountability Additional information about this option: EFTA00802889  pit SYSTEMS COMPANY OVERVIEW: The Iron Edison Lithium Iron Battery is the newest technology in energy storage batteries. Fully compatible with industry-leading inverters and charge controllers, Iron Edison's Lithium Iron Batteries offer the safest, simplest and most dependable energy storage solution for off-grid and grid tied battery backup applications. Our Energy Storage Solutions: Assembled in Denver, CO, Iron Edison Lithium Iron Phosphate Batteries are a complete energy storage system. The integrated Battery Management System (BMS) monitors and regulates each cell in the battery bank to provide perfectly balanced charging and discharging while guarding against over-charge, over-discharge and thermal overrun situations. Internal DC disconnects provide battery protection and isolation. The entire lithium iron solar battery system is contained in a rugged metal enclosure. FEATURES: Lithium Iron solar batteries have all the advantages of modern power storage. A Lithium Iron battery's electrochemical capacity allows it to store more energy than lead acid. If you're looking for energy storage for your residential solar panels and UPS systems, lithium batteries are your best options. Furthermore, due to its chemical composition, we're able to design smaller but more efficient batteries. SAFETY: Lithium Iron batteries have superior chemical and thermal stability than other Lithium-ion batteries. It remains cool at room temperature while Lithium-ion heats up faster and may suffer thermal runaway under similar charging conditions. LEAD ACID REPLACEMENT: As solar energy becomes a popular power source, lithium solar batteries will become the standard option for manufacturers and installers. Replacing your lead-acid batteries with lithium iron is a step in the right direction. As such, if you switch solar panel systems, your Iron Edison Lithium Iron Phosphate Batteries will still be useful. We have lithium batteries at 48v, with capacities up to 5,600 Ah. 1 EFTA00802890  pry SYSTEMS BATTERY LIFE: Supporting a daily 80% depth of discharge, Iron Edison Lithium Iron Batteries should last 16 years or more (6,000 cycles), and comes with a 10 year warranty. INVERTER CHARGER BMS COMPATIBILITY: The Iron Edison Lithium Iron Battery is designed to be fully compatible with industry leading inverters and charge controllers like Schneider, Outback, Magnum, MidNite Solar and SMA. Unlike the Tesla PowerWall, Iron Edison's LiFePO4 battery comes in industry standard 48 volt configurations making it a direct replacement for lead acid battery chemistries. FEATURES: • 100% Maintenance Free • Sealed Battery - No Venting Required • Small Footprint - Typically 1/4 the size & weight of flooded batteries • High Charge & Discharge Rate • Integrated On-Board Digital Battery Management System • Communications from our battery to Outback, Schneider Electric, and SMA using MODBUS and CANBUS communication protocols • Our BMS controls charge rate, request for generator and grid charge • Overcurrent Protection (class t fuse) and DC Disconnect (Gigavac contactor) built into the battery • Steel Enclosure, made in Colorado • 400 Ah - 2,000 Ah Capacities Available at 48 Volts DC. • Proven battery management and communication with existing SMA Sunny Island System, Multi-Cluster Box, SMA grid-tied inverters and existing solar EFTA00802891  pit SYSTEMS *10 year warranty manufacturer's warranty lyr workmanship warranty Lead time on this battery would be about 3-4 months from deposit.
