Which end of the photovoltaic panel is the positive pole
Generally, the leading wire of the left box corresponds to the negative pole, and the right side corresponds to the positive pole, but this depends on whether the module is placed vertically or horizontally, so you must look for the laser-engraved marking next to the cable gland.

PV inverter warranty start time
1 Warranty start date: The warranty period starts from the 90th day after Huawei ships the products or the date when Huawei receives the service request for the product, whichever is earlier. If the customer/partner requires a different start date, for example PAC, the warranty start date shall not be later than the 180th day after the shipment date.
FAQs about PV inverter warranty start time
How long is a power inverter warranty?
Usually, inverter manufacturers offer a standard warranty period of 10 years for string inverters, whereas module-level power electronics (MLPEs) like microinverters or power optimizers offer 25-year warranties. In the case of an extended warranty period, few manufacturers allow you to purchase extra warranty time for their products.
What is a solar inverter warranty?
Here's a breakdown of solar inverter warranties by major manufacturers: When you choose Enphase microinverters, you're backed by the Enphase warranty, which gives you 25 years of coverage—matching the lifespan of most solar panels. That means your entire solar system is protected long-term.
What factors affect the warranty period of an inverter?
Inverter Type: The warranty period is influenced by the type of technology used. For instance, microinverters have longer warranties when compared to string inverters. Additional factors such as efficiency, voltage, lifespan, installation angle, and irradiance system loss can affect the warranty period.
How long does a SolarEdge inverter warranty last?
Most standard string inverter warranties last between 5 and 12 years, and inverter failure during this period can result in complete system shutdown, leading to lost solar production and unexpected costs. A longer SolarEdge inverter warranty can help protect against expensive replacements and provide peace of mind.
How long is a microinverter warranty?
Microinverters often include a 20- to 25-year microinverter warranty. Because microinverters are installed on individual panels, a single inverter failure won't shut down your entire system. Many microinverter warranties cover both parts and labor, making repairs easier if issues arise.
Do inverters have extended warranties?
Some manufacturers offer extended warranties for an additional cost, but coverage varies. While a standard inverter warranty typically covers defects and failures, extended warranties may extend coverage for parts, but not always labor or service costs. Some manufacturers provide refurbished replacements instead of new units.
