Confirm grid mode
Decide whether the site needs grid interaction, backup operation, independent off-grid supply or generator coordination.
Solar inverter comparison
Compare hybrid and off-grid inverters from 1.2 to 16.8 kW.
Compare phase, battery platform, PV input and application before opening the model-level technical page. Final selection requires the actual load, grid conditions and system architecture.

Selection logic
Choose architecture before model number.
Measure load and surge
Use simultaneous running power, motor starting demand, daily energy and required backup time.
Match the complete system
Confirm PV strings, battery current and communication, protection, voltage, phase and installation conditions together.
Commercial decision guide
Use one project brief to compare inverter quotations.
A lower inverter price may exclude battery communication, generator coordination, protection, monitoring or required documentation. Give every supplier the same inputs and compare the exact model and delivery scope—not only rated kW.
| Quote input | Why it changes selection | What the buyer should provide |
|---|---|---|
| Grid and phase | Separates grid-interactive, backup and independent off-grid architectures and rules out the wrong phase platform. | Country, site voltage, single/three phase, outage pattern and export requirement |
| Running load and surge | Sets continuous output and short-duration motor-starting demand. | Simultaneous kW, largest motor or compressor, starting method and priority loads |
| Battery requirement | Determines voltage, charge/discharge current, communication and backup-energy constraints. | Exact battery model if selected, backup hours, daily cycles and future expansion |
| PV array | Must fit MPPT voltage/current, temperature-adjusted open-circuit voltage and input-power limits. | Module datasheet, modules per string, string count and site temperature range |
| Operating environment | Changes enclosure, mounting, thermal and protection requirements. | Indoor/outdoor location, temperature, humidity, dust, altitude and installation space |
| Commercial scope | Prevents unlike-for-like quotes that omit accessories, documentation or commissioning support. | Quantity, destination, monitoring, protection, cables, documents and support required |
Buyer questions
Compare the electrical system—not only kW.
What is the main difference between a hybrid and off-grid inverter?
A hybrid inverter is generally selected where grid interaction, battery storage and backup operation must be coordinated. An off-grid inverter is generally selected for systems designed to operate independently of the utility grid. Exact functions vary by model.
Should inverter power be selected from total appliance wattage?
Use the maximum simultaneous running load, the largest starting surge, phase arrangement and operating strategy. Adding every appliance rating together may overstate or understate the actual requirement.
Can a 48 V battery be connected to every 48 V inverter?
No. Confirm voltage range, charge and discharge current, BMS protocol, firmware, protection, cables and approved inverter settings.
Does the maximum PV voltage determine the solar array size?
Not by itself. String design must also respect MPPT operating voltage, starting voltage, input current, temperature-adjusted open-circuit voltage, power limits and local installation requirements.
