What should I do if the inverter will not power on?

2026-10-12

Please check: 1. Whether the battery voltage is normal (not depleted); 2. Whether the battery polarity connection is correct—never reverse positive and negative; 3. Whether the DC breaker/fuse is on or blown; 4. Whether PV input is normal. If all checks pass and it still does not power on, please contact technical support.

What should I do if the inverter shows an error code or red light?

The inverter LCD screen or mobile app will display a specific error code. Common faults include: grid over/under voltage, PV insulation fault, over-temperature, fan failure, etc. Please record the error code and troubleshoot according to the manual. If unresolved, contact technical support with the model and error code

How long is the inverter warranty period?

The standard warranty is typically 2-5 years, and some premium grid-tie inverters can be extended to 10 years. The warranty period starts from the date of delivery. Non-human-caused defects are covered with free repair or parts replacement.

Can the inverter connect directly to solar panels?

Off-grid inverters usually have a built-in MPPT solar charge controller and can connect directly to PV panels. Grid-tie inverters also connect directly to PV strings. However, pure DC-AC inverters (without MPPT) require a solar charge controller between the panels and battery, and then the battery connects to the inverter.

What battery types are compatible?

Hybrid inverters are compatible with lead-acid batteries (flooded/gel) and lithium batteries (LiFePO4). The battery type can usually be selected in the settings menu. Lithium batteries are recommended for longer lifespan and higher efficiency, but the inverter itself does not include a battery.

What information is needed to customize an inverter?

We need: 1. Required power (kW); 2. Output voltage and frequency (110V/220V, 50/60Hz); 3. Battery voltage type; 4. PV input requirements (MPPT count, max voltage); 5. Communication/monitoring requirements; 6. Brand and packaging requirements; 7. Target market and required certifications.

What is the IP rating? Can it be installed outdoors?

Grid-tie inverters typically have IP65 protection and can be wall-mounted outdoors. Off-grid/hybrid inverters are often IP20/IP43 and are recommended for indoor installation in well-ventilated locations or distribution boxes. Ensure adequate ventilation space during installation, avoiding direct sunlight and water immersion.
