The HC-PV Long Gray inverter converts DC battery power into stable AC power for off-grid solar systems, backup power systems, and battery energy storage applications. It is suitable for users who need reliable power conversion for household appliances, workshop equipment, farm loads, pumps, motors, tools, and other compatible electrical devices.
Compared with the Short Blue model, the Long Gray version is positioned more for professional project use, fixed installation, and neutral product-line presentation. Its gray appearance gives distributors and system integrators a more industrial and application-focused inverter option for solar backup and off-grid power markets.
Key Features
Long Gray professional housing
The long gray design gives this model a clean, industrial appearance suitable for project supply, equipment rooms, workshops, and distributor product lines.
Pure sine wave output
Provides stable AC power for compatible appliances, tools, electronics, and battery-based backup systems.
Low-frequency inverter design
Suitable for applications that require stronger load adaptability and better support for startup surge demand.
Designed for fixed solar backup systems
A practical choice for home backup, rural electricity, workshop power, farm power, and off-grid solar installations.
Suitable for demanding loads
Can be selected for pumps, motors, refrigerators, compressors, and tools when the correct model is matched.
B2B supply and OEM/ODM support
Hongyi Electric supports distributors, installers, wholesalers, system integrators, and private-label buyers.
Typical Applications
The HC-PV Long Gray inverter can be used in off-grid solar systems, home backup power, rural power projects, farms, workshops, small commercial backup systems, battery energy storage systems, and solar-plus-battery installations.
It is especially suitable for buyers who need a low-frequency pure sine wave inverter for fixed or semi-fixed systems rather than compact portable use.
How to Select the Right Model
Before ordering, confirm the load power, startup surge power, battery voltage, AC output voltage, frequency, backup time, installation space, and solar charging requirement.
For pumps, motors, compressors, refrigerators, and workshop tools, check both rated power and startup surge power. For B2B orders, provide the system configuration and target market so Hongyi Electric can recommend the right inverter model.
Why Choose Hongyi Electric
Hongyi Electric supplies low-frequency pure sine wave inverters, solar charge controllers, portable power products, and power conversion solutions for global renewable energy markets. We support wholesale supply, OEM/ODM cooperation, private-label projects, and application-based model selection.
