Accessory RFQ checks
A reliable accessory specification connects the exact part to a supported inverter, one-line, firmware and required operating result.
Required function
Define monitoring, remote communication, export limitation, PLC aggregation, rapid shutdown, AC combining or cloud portfolio management; separate visibility from automatic control and safety functions.
Exact compatibility
List complete inverter and accessory codes, generation and firmware; request the current supported-device matrix, required connectors, gateways, meters/CTs, transmitters, cables and licenses.
Electrical topology
Provide phase/voltage, inverter quantity/output, AC/DC one-line, point of common coupling, meter and CT position/ratio/direction, RSD string/module arrangement, protection, grounding and conductor data.
Communication architecture
Map ports, physical media and protocol, addressing, device quantity, cable/power-line limits, gateway/controller, internet path, server region and third-party SCADA or API requirements.
Data, cloud and fail-safe
Define data frequency/retention/export, user roles, remote commands, credentials, cybersecurity, network loss, local fallback, export-control failure mode, subscriptions and long-term service expectations.
Evidence and commissioning
Request exact datasheet/manual, listing/certificate scope, wiring drawings, firmware/settings record, functional/shutdown/export tests, training, warranty/SLA, replacement, release status and lead time.
