About this file
This is a solar equipment requirements specification document that establishes technical standards for three categories of DC power system installations based on capacity levels.
The document specifies component requirements across three system sizes: Small Systems (200W–2000W), Medium Systems (5KW–100KW), and Large Systems (100KW–1MW). Small systems require Tier 1 solar modules (200W–450W range, UL 61730 certified), MPPT charge controllers with Modbus RS485 or TCP/IP remote alarms, deep-cycle Lithium Iron Phosphate batteries (12V or 24V, UL 1642 or UL 1973 certified), and 1000W–3000W RV/Mobile inverters with UL 458 certification. Medium and Large systems mandate higher capacity Tier 1 modules (450W–600W range), IEEE 2030.7-compliant microgrid controllers with remote alarm capabilities, advanced battery storage options including hybrid super capacitors (UL 1973, UL 9540, UL 9540A certified), and string or central inverters (UL 1741SB or UL 1741SA, IEEE 1547 compliant). All system sizes require UL 4703-certified photovoltaic wiring, UL 6703 MC4 connectors, and UL 2703-certified fixed ground mount racking systems. Medium and Large systems additionally require UL 1741-certified solar combiner boxes. Large systems specifically mandate containerized battery energy storage system options. The specification ensures interoperability through standardized communication protocols and manufacturer-provided Modbus register documentation across all applicable components.
