I bought 2 wall mounted solar batteries. System was easy to hook up and easy to use. I do wish there was a better explanation of how to properly run the communication cables for multiple batteries. This would really help for people new to your products, but in all we are super happy.
Wilma Hasek –
That is a solution, not necessarily something everyone likes.We already have “market price” power contracts that adjust according to the spot prices. Only problem is, when the price goes up wildly, people have no options to shut down. Every year it’s the same. Just before Christmas the power companies start calling you and cajoling you to switch over to “cheap” market priced contracts with only “six cent power prices” – yeah, at night when I’m not using any. At some point in the future when the supply variation becomes bad enough, they will stop selling regular fixed price contracts and push all of the problem onto the consumers, who can deal with it no better.Last year we had super high power prices for a while (28 c/kWh average, 120 c/kWh peak), and families with “cheap” market priced contracts were suddenly facing 1000 EUR power bills. Some households were turning down heat, hot water and stopped cooking at home for a month. Can these people also afford the batteries to bridge a week or a month of shortfall?

I have installed this power storage system completed three days ago as an off grid system and it has been operating without any problems. now it supplies enough power from the solar panels in the daytime to charge my ev car during the night after I get back home. I am very impressed by efficient of this powerwall.
