SolarEdge vs. Enphase: comparing warranties for leading inverter manufacturers

If you want to make sure your solar panel system is operating as efficiently as possible, you are probably considering either power optimizers or microinverters (collectively known as “module level power electronics,” or MLPEs). In the United States, SolarEdge is the leading power optimizer manufacturer, while Enphase leads the pack for microinverters.

Deciding which inverter to choose can be difficult, and product warranties make a difference. In this article, we’ll compare SolarEdge’s warranty offerings with Enphase’s warranties.

SolarEdge warranty vs. Enphase inverter warranty: which is better? 

Both SolarEdge and Enphase offer a strong 25-year warranty for their MLPEs. However, SolarEdge’s inverter itself is covered for only 12 years. SolarEdge does offer the option to pay for an extended warranty for its inverters – this might be be worth it if you choose a SolarEdge system because central inverters don’t typically last as long as power optimizers or microinverters.

Read on for a detailed breakdown of each company’s warranties.

SolarEdge warranties for power optimizers, inverters, and monitoring

If you install a solar panel system with SolarEdge, there are separate warranties to cover each SolarEdge product: 

  • Power optimizers (roof equipment): 25 years
  • Central inverters, meter, and modem (wall equipment): 12 years
  • Communication equipment: 5 years

All of SolarEdge’s warranties start either 4 months from when the products are shipped from SolarEdge or when the products are installed (whichever is earlier).

SolarEdge covers between $125 – $225 in any labor costs and offers the option to purchase an extended warranty to 20 or 25 years. You can also transfer its warranty easily to new system owners at no cost. To learn more about SolarEdge’s inverter warranty, read our complete review.

Activating and using your SolarEdge warranty

If your SolarEdge power optimizer, inverter, or other product has a defect and you need to activate your warranty, you need to share your product’s serial number, a copy of the purchase receipt or warranty certificate, and a description of the problem.

Once they have verified that your product is eligible for repair under the warranty, the company will repair the product (at your property or at their own facility), give you a credit towards a new product, or give you a replacement product.

SolarEdge covers the cost of shipping products for repair, as well as some labor and material costs. However, if they need to send someone to repair your product on-site, you may have to pay travel and boarding costs.

Enphase warranties for microinverters, monitoring, and wall equipment

Solar panel systems with Enphase microinverters may have additional Enphase components as well. Each of these is covered by a separate warranty:

  • Microinverters (roof equipment): 25 years
  • IQ Gateway and IQ Combiner (wall equipment): 5 years
  • Communication equipment: 5 years

Most of Enphase’s warranties start either on the date the products are registered with Enphase or when the products are installed and activated (whichever is earlier). To learn more about Enphase’s inverter warranty, read our complete review.

Activating and using your Enphase warranty

If your Enphase product has a defect and you need to activate your warranty, the company will either repair or replace the product or give you a refund. Enphase’s warranty covers the cost of new equipment and shipping products for repair. Similar to SolarEdge, they also cover some labor costs.

SolarEdge vs. Enphase battery warranties: which is better?

In addition to inverters, Enphase and SolarEdge also offer storage solutions. Both the Enphase IQ Battery and SolarEdge Energy Bank are covered for 10 years. However, if you exceed the cycles or throughput clause for Enphase before the 10 years your warranty will no longer apply, while SolarEdge does not include a cycles of throughput clause in its warranty.

    Just to be clear about Enphase’s Warranties. Please see quoted statements below from the actual warranty. Links to Enphase website and warranty coverages will be provided below.

    The Limited Warranty Period for Enphase IQ MicroInverters is 25 years.
    The Limited Warranty Period for Enphase’s “Envoy” (the monitoring unit and service) is 5 years.

    Under section 8. “Limited Warranty Limitations and Exclusions”, it states: “ This Limited Warranty does not include any cost of labor related to (i) un-installing Covered Product; (ii) re-installing a repaired or replacement product, or (iii) the removal, installation or troubleshooting of the Covered Owner’s electrical systems”.

    Both the 25 year microinverter warranty and the 5 year Envoy warranty are to replace defective parts, and do not cover any associated Labor.

    Enphase has a separate Standard Labor Warranty for reimbursement of service companies for their labor costs, and it states that the “reimbursement amounts” for “each truck roll to a site for repair is $125”. It states that the “reimbursement amounts” for “each eligible defective product is $25”.

    The length of the limited Labor Warranty as stated by Enphase is: “ Labor can be claimed for the first 2 years from the system install date.”

    So, to summarize, Enphase MicroInverters come with a 25 year manufacturers “parts” warranty. Enphase monitoring comes with a 5 year manufacturers “parts” warranty” and the Labor Warranty is for a total of 2 years.

    In contrast, SolarEdge Warranties on both the power optimizers, as well as the Inverter unit on the side of the home are as follows.

    The Limited Warranty on the SolarEdge Power Optimizers is 25 years.
    The Limited Warranty on the SolarEdge Inverter is 12 years
    SolarEdge offers an extendable Inverter warranty of up to 20 or 25 years, so that both Power Optimizers and Inverter can be warranties for 25 years each.
    The Limited Warranty on the StoreEdge (battery backup) unit is 10 years.
    The Limited Warranty on does not include the cost of labor.
    SolarEdge however does have a labor reimbursement policy. Labor can reimbursed for 5 years on the Inverter, and 12 years on the power optimizers.

    Contractor Comment:

    Solaredge is a chronic failure product.

    We installed 20 SolarEdge systems 5 years ago. We have completed at least 35 RMA trips and trouble shooting calls on the 20 SolarEdge systems so far. We have not charged our clients anything so far for all our go backs and replacement of defective SolarEdge materials.

    SolarEdge pays little or nothing for us fixing their defects. We take a loss on every service call we complete for them. Bad mistake choosing to try SolarEdge.

    Also of note:

    RMA reimbursement to installer (may affect homeowner):
    -SolarEdge pays installers for each RMA for the duration of the product warranty.
    -Enphase pays installers for each RMA for 2 years only

    Transfer of ownership (sell your house):
    SolarEdge: No charge
    Enphase: $399 per transfer

  4. Adam

    Enphase warranty covers labor for 25 years. Solar Edge has a 12 year warranty in the actual inverter but they hide it by saying optimizers have a 25 year. Inverters fail sometimes and with Solar Edge you lose the whole system and have a 12 year warranty. These products are similar by fundamentally not fair to say they’re equal

  5. Alan Adams

    On my emphase system I have 12years labor, life time monitoring system. After than it’s a 50.00 labor fee for the remaining time of the 25year warranty
