Answers to common questions about SMA inverters, generator sizing, and cost-saving decisions from a procurement perspective. [...]
SMA vs Growatt inverter — The myth: "All modern string inverters are built the same — pick the cheapest one and you'll get the same DC-to-AC conversion, just with fewer features." That statement sounds plausible until you look at where… [...]
SMA vs Sungrow inverter — You’re comparing 98.5% vs 98.6% peak efficiency, and you think that tells you which inverter costs less over 15 years. It doesn’t. [...]
SMA vs Huawei inverter — Popular claim: “Huawei inverters have higher efficiency, so under the same load and battery, they will run longer.” At first glance, the numbers support it: the Huawei SUN2000-8KTL-M1 quotes a max efficiency… [...]
SMA vs Growatt inverter — You sized the string for STC irradiance. You checked the max input voltage. Your designer signed off. [...]
SMA vs Sungrow inverter — You sized a 9 kW array with a Sungrow SG8.0RT (8 kW, 98.5% max eff). Passes NEC. Passes commissioning. Then a client adds an EV charger, or a tenant plugs in a 6 kW welder. The inverter clips—hard. [...]
