Q.
What is an off-grid inverter?
-
A.
Off-grid inverter is a device that convert direct current (DC) - from sources like batteries, solar panels, etc. - into alternating current (AC) - the electricity used by household appliances. Their most critical characteristic is that it is not connected to the public power grid.
Main Features:
- • Completely independent from the power grid.
- • Must be equipped with batteries.
- • Possess intelligent management functions.
- • iverse output waveforms: Pure sine wave inverters or modified sine wave inverters.
-
Q.
What are the main application scenarios for off-grid inverters?
-
A.
Off-grid inverter systems are ideally suited for use in the following locations without grid access or with an unstable power supply:
- • Remote areas: Mountains, ranches, islands, field workstations.
- • Mobile power supply: RVs, boats, campers.
- • Emergency backup power: Serves as a backup power source for homes or critical facilities to cope with sudden power outages.
- • Specific off-grid applications: Solar street lights, traffic monitoring systems, communication base stations, etc.

Q.
What is the difference between Off-grid Inverter and Grid-tied Inverter?
-
A.
To help you understand more clearly, here is a comparison table:
Feature Off-Grid Inverter Grid-Tied Inverter Grid Relationship Completely isolated from, and not connected to, the public grid Must be connected to the public grid to operate Energy Storage Must be equipped with batteries Typically not equipped with batteries (in grid-tied PV systems) Primary Function Converts DC from batteries to AC for self-use Converts DC from solar panels to AC and feeds it into the grid Power During Outage Yes. Continues to supply power if batteries have charge, even during a grid outage No. Automatically shuts down during a grid outage for safety reasons Application Goal Achieve energy self-sufficiency, solve power absence/scarcity issues Save on electricity bills and earn revenue by selling power (e.g., "Poverty Alleviation via PV", "Feed-in Tariff" schemes)

Q.
What are the common wattages of basic household devices?
-
A.
Taking common household appliances as examples:
- • a rice cooker (approximately 800W)
- • a washing machine (approximately 500W)
- • a refrigerator (approximately 150W)
- • an air conditioner (approximately 1500W)
- • an induction cooker (approximately 2000W)
- • lighting (approximately 200W).
-
Q.
If I install the system myself, do you provide installation guides, videos, or technical support?
-
