SolarMax is offering a free warranty upgrade from two to five years on its central inverters, with other guarantee extensions also being made available, according to the company. All material, travel and labour cost will be covered by the company if the purchased product is within its warranty period, and all that is required to avail of the free extension is that the inverters be registered on SolarMax’s database.
If the central inverters are registered on the company site within the first three months after installation, the standard warranty is automatically extended to five years. The company is also offering optional extended warranty coverage plans, which are now available for all string and central inverters and can extend to as long as a 25-year guarantee.
