Let me clear up a few misconceptions. Sol-Ark is owned by US Veterans, not Deye. The engineers at Sol-Ark designed the Hybrid-Inverters and Deye is a manufacturer of our innovations. We worked with them for 7 years and gave them much of the IP to assist in the development of their grid-tied and microinverter options. 99% of the features, software methods, GUI, and hardware was done by us in the US.
So why would we give away IP? Our mission is affordable energy independence for family homes and businesses. We allowed Deye to sell elsewhere, in accordance to our agreement, so it could lower the costs for everyone and we pass that on.
Our Veteran owners and engineers fought around the world for the love and respect of the US people. Our focus is here now.
Why is there a higher price for Sol-Ark? #1) We paid millions in development, prototypes, debug, and cleaning up manufacturing mistakes. #2) We spent 100's of thousands in UL certificates and engineering time. #3) We warranty and repair our systems. #4) We pay a 25% tariff on these inverters. Others you mention in this blog are falsifying the country of origin to only pay 1.5%. #5) Features and functions of Sol-Ark products are significantly different for the US market and we continuously improve. #6) We designed it for ourselves and DIYers and found this requires a tremendous amount of support. Our rapidly growing engineering team is committed to their success.
Thanks for letting us know about these Stole-Arks. What good is a $30-50K ESS system that fails?
Remember our mission of affordability. We realized long ago that reducing the cost of the inverter was not the complete answer. Below are the largest expenses of an average installed (not DIY) ESS system = $45K before credits.
1. Battery = $13,000
20kWh x $650/kWh
2. Install = $10,000
10kWpv x $1/W
3. Financing = $7,000
$38K x 18%
4. Inverter = $6,000
8000W x $0.75/W
5. PV Panels = $5,000
10,000W x $0.50/W
6. Misc / BOM = $4,000
Each ESS (Batt + Inverter) = $19K. If we can use a single ESS to backup the entire home instead of 2+, that’s a massive savings. If we can make it 2-3X easier to install, we can bring down that expense. If we can make the battery last longer, that saves. We are currently engineering communications for Utilities that allows for “renting” your ESS ~60 times a year and pay you ~$1K/5KWh/year!
You will see some amazing innovations from Sol-Ark in 2021. Most of these will be Made in the USA as our new facility will be completed.
The Deye/Sunsynk Hybrid is a copy of a Sol-Ark, not the other way around.
