Powerwall 2 vs Others

Pika was bought by Generac. They have supposedly cost reduced the electronics by having them made by their supply chain in Vietnam instead of domestic American manufacturing. I have not seen the new literature from Generac nor seen a quote.
I don't know what Sonnen is like these days. Last time I looked into it, the product was basically a pretty cabinet with an Outback inverter and LiFePO4 batteries inside with a custom control system.
I don't think either of these are anywhere near cost competitive on a per kW or per kWh basis with Tesla. However, since Sonnen is based on Outback, they should have good generator support, if that's something you really need.
Thanks, Wasn't aware of the buyouts, seems like the industry is consolidating. Found the Generac's version Generac Power Systems - Portable Generators and Inverter Generators for Camping and Recreation. Looks like the Pika except for the color.
So Generac a company that provides gas generators and Shell a oil and gas company is buying clean energy companies. What's next Exxon Mobil buying SunPower?

What's your use case and your budget? I have a Magnum Energy 4448PAE with 2 banks of golf cart batteries. Not ideal for load shifting but they do great for backup power. I've had them for ~5 years now. The thing I really like about the Magnum is it's a tank and the system is pretty cheap. I'm considering adding a bank of L16 batteries for $2400. Trojan has a line of 'premium' flooded batteries that boast an 8 year 1900 cycle life to 50% DOD. $2400 for ~20kWh of storage seems like a pretty good deal to me...

I'm considering a LG Chem battery system as well as Telsa Powerwalls. The local company who installed our two solar arrays a few years ago switched from being an Authorized Independent Tesla Powerwall installer to LG Chem. Our local utility company told me they have more rebates available for LG Chem as opposed to Tesla. If the systems are pretty close in features and price, I'll probably go with the local company because they have truly excellent customer service...
Just looked up the Pika and it has UL 9540, UL 1973, UL 1642, CSA 22.2 certs and the Sonnen has UL 9540, UL 1741 (inverter), UL 1973 (batteries), and FCC part 15 Class B.
