Is $9,500 to install a 6.75kW solar system with Sigenergy inverter and 15kWh battery a fair price?
Project Details
I got a couple of offers for very similar prices here in Lithuania. I'm trying to decide if the Sigenergy system is a no-brainer at this price point. The seller mentioned I'll have fewer issues with Sigenergy because it's an all-in-one system, whereas Solis and Foxess require constant tinkering with settings. From what I've gathered online, Sigenergy also seems to have more features, like working as a proper house UPS.
