Commercial Hybrid Inverter RFQ Checklist: MPPT, Battery Voltage and Grid Code
A commercial hybrid inverter quote can fail even when the kW number looks right. Suppliers still need PV string details, MPPT needs, battery voltage range, grid-code requirements, backup behavior, monitoring scope, and quantity. This checklist helps buyers send a quote-ready brief instead of a loose model request.
Name the target kW class, but leave room for model adjustment
Start with the target AC power range, such as 29.9-50 kW or 50-100 kW. Then explain the site goal: rooftop self-consumption, C&I storage, peak shaving, weak-grid support, or backup for critical loads. A supplier may recommend a nearby model if the battery voltage, PV oversizing ratio, or grid-code variant makes the first model a poor fit.
Send PV DC size and roof complexity, not only inverter kW
For rooftop projects, list PV DC capacity, module watt class, string count if known, roof orientations, shading zones, and MPPT needs. A simple flat roof and a multi-orientation commercial roof may both ask for a 50 kW hybrid inverter, but they do not need the same MPPT planning. If a module page or layout drawing exists, include it in the RFQ.
Battery voltage window must match the selected ESS
Commercial hybrids are often tied to a specific battery voltage range. State whether the ESS is 48V LV, 150-800V HV, 200-900V HV, 600-1000V HV, or another platform. If you already selected rack batteries, send the battery model and target kWh. If not, send target backup hours or peak-shaving kWh so the inverter and storage can be recommended together.
Grid code, phase type, and backup behavior affect the quote
Include destination country, grid voltage, phase type, required certifications or grid-code settings, export limit rules, and whether the project needs UPS behavior, black start, generator input, or off-grid parallel operation. These details can change model variant, accessories, monitoring scope, and commissioning support.
Clarify monitoring, EMS, and communication boundaries
Ask whether the quotation includes monitoring dongles, smart meters, CTs, export limiting devices, EMS coordination, and communication protocol support with the battery BMS. For multi-inverter or storage-heavy C&I sites, unclear communication boundaries are a common source of commissioning delay.
Commercial fields for an export-ready inverter RFQ
Add quantity, destination port, Incoterms, required documentation, branding or distributor needs, delivery window, and whether the request is for one project or a repeat line-card program. If the buyer needs PV modules, rack batteries, or mounting in the same shipment, state that early so the quotation can be scoped as a system rather than a standalone inverter.
Minimum RFQ inputs for commercial hybrid inverters
Include destination market, target AC kW model, grid voltage and phase type, PV DC size and module class, MPPT/string plan or roof layout, battery voltage window and target kWh, backup or peak-shaving objective, required grid code/certifications, monitoring/export-limit needs, quantity, Incoterms/port, and timeline.
Request a commercial hybrid inverter quote
Send target kW, PV DC size, MPPT/string plan, battery voltage window and kWh target, grid code, destination market, quantity, and Incoterms. We will reply with a matched inverter and storage scope.
