I'd love to know why you'd choose an EG4 18k (which is actually a 12k AC inverter, with a questionable track record on support and warranty) over a Sol-Ark 15k (which is actually a 15K AC inverter, and has tech support that responds) now that Sol-Ark dropped the price on 15ks to sub $5,000 MSRP.

I'd rather land wires in a Sol-Ark, it has better support, it has a higher AC output, it has a higher battery charge rate, and it's the same price.
