String的是5kw的inverter. 板是Longi and Trina。我们已经决定不用这家，只有5年installation warranty. ...
Most companies will match their warranty to the period of the inverter manufacturer’s warranty ie 5 or 10 years. Lifetime warranties are generally used as a sales tactic, as are companies that ‘upsell’ or ‘period match’ during the sales process. The fact is a warranty comes with an associated cost, and needs to be put in writing, so any change in warranty will require a change in the price and/or contract.
Be aware that a long warranty is quite often not the best warranty. History has proven time and time again, that the longer the warranty period, the greater the chance of that company collecting the money and disappearing. If it all sounds too good to be true, it probably is! |
