Common questions
Frequently Asked Questions
Find quick answers about choosing an INV / INW off-grid hybrid inverter. Final settings and compatibility depend on the exact model and system design.
How do I choose the right inverter output rating?
Start with the continuous power and starting surge of the loads you want to run. The models shown here range from 1.2 kW to 12 kW. Battery voltage, PV input limits and the required backup duration should also be checked before selecting a model.
Can these inverters work with lithium and lead-acid batteries?
The supplied product information lists support for lithium and lead-acid batteries. Check the exact battery voltage and, for lithium systems, confirm BMS communication and charging settings for the selected inverter model.
Can the inverter supply power when the grid is unavailable?
These are off-grid hybrid inverters designed to combine solar PV, battery operation and utility input for backup applications. Available operating modes and battery requirements vary by model, so confirm the proposed wiring and configuration before installation.
What PV input voltage should my solar array use?
The allowable MPPT voltage range is model-specific. The product cards above show the published ranges for each model; also verify the maximum PV power, open-circuit voltage and current against the final datasheet before sizing your array.
Is transfer time under 10 ms for every model?
The supplied specification lists a switching time of less than 10 ms for INV 1200-12 and INV 2000-12. Ask for the current datasheet if transfer time is critical for another INV or INW model or for a sensitive load.
Which models support parallel operation or remote monitoring?
The supplied INV / INW series material identifies parallel capability for selected higher-output models, while WiFi monitoring is listed as optional on several models. Confirm the permitted number of units, accessories and firmware version for the exact configuration you plan to order.
How can I get a datasheet or installation manual?
Use the Download Center request buttons or the inquiry form below. Please include the model number, destination country and project requirements so YINEN POWER can provide the current documents for your configuration.
