B2B FAQ
Is the output pure sine wave or modified sine wave?
It depends on the model and is listed in Key Specifications above. Pure sine wave is the right choice for motors, compressors and sensitive electronics.
Can it start a motor or compressor?
Yes, within the model’s rating — but size against starting (inrush) current, not running current. Send the load profile and we check the starting-current margin.
What DC input range and efficiency does it have?
Input range and efficiency are model-specific and listed in Key Specifications above. Give us your battery bank voltage and we confirm the model that stays in regulation.
Can I choose the AC output socket or hard-wire it?
Yes. We can supply an AC socket, a terminal block, or a hard-wired output to suit your installation.
Do you offer Custom Branding and sample development?
Yes. Custom Branding is available on the product label, housing and packaging for OEM and ODM programs. Send your specification and target quantity; we confirm the configuration, sample lead time and quote, then move to production once the sample is approved.
