    Any recommendations?

    2000W is possible to get. But I think the most important thing is that YOU MUST know clearly what kind of battery is equipped with, LFP or NMC. All people know NMC is short life than LFP. Usually, NMC is about 1000 life cycles(some maybe only 700 cycles), but LFP is 3000 to 5000 life cycles. That is different and matters much. A longer life span means saving money. Better means more than money. That is my tip. Check the latest Tesla Models equipped with what kind of battery, to know the battery tech, that will be a light for you and helpful.

      I disagree with EverAzure about the shorter life of NMC. I have a Tesla NMC battery that is six years old and has been cycled 600 times and it still has 85 percent of it's original capacity. The capacity has declined very little after the first year. This battery has significant cooling and temperature controls that you won't find in a solar generator. For that reason I would recommend an LFP battery.

        NMC has a shorter lifespan than LFP, not what I said, it's basic science. For solar products, I like LFP, safer than NMC, that is fact. That is why Tesla choose LFP for Model 3. But some high level models are still equipped with NMC.

          I do not know for a fact that NMC has a shorter lifespan. I have seen some research from Dalhousie University about how to extend the life of NMC but nothing that compares that to LFP. I also know that Tesla hired Professor Jeff Dahn, from Dalhousie, for some projects on battery design and management, but I have not followed the topic lately. What is the basic science that you refer to? I have seen some research, but it did not mention the science. It does have a lot to do with how a pack is managed. Certainly short life is true with my cell phones, but I make no attempt to manage them like I do with my EVs and they have nowhere near the sophisticated battery management for cooling and heating that my EVs have. .

          I do agree LFP is safer than NMC, and I understand that science. My 2019 Model 3 SR+ is NMC, but I am confident Tesla has mitigated the risk better than some others. Both my sister in law and my ex wife had recalls on their cars with LG packs. I know for sure the Model 3s manufactured in China are LFP and possibly Germany but have not heard of any in the USA. Reportedly some Model Ys are coming out of Austin with LFP packs but I may have that confused with the new tab less cell which I think is still NMC. It is evolving rapidly. There is a royalty agreement expiring in 2022 or 2023 which may facilitate more LFP manufacturing coming to the US.

            Yes. NMC has higher energy density than LFP, but LFP has more advantages in terms of safety and service life. Especially security, which is a concern of almost everyone. As I know, in the U.S. and Europe, the new Model 3 is made in China equipped with LFP batteries, and recently Ford also purchased Chinese LFP batteries. BMW and Volkswagen are also sourcing LFP batteries from China. NMC for energy storage market is not the best option, that is why market forecast experts say LFP will overtake NMC by 2028.

              While that sounds like a great plan I hope those LFP batteries will be made in the US. If not then those EV's won't be able to get the rebate from the government because the batteries will need to be made in the US to get that rebate.

                But...but...Elon Musk can not make it in the USA, because of the cost, he is a businessman bro. You know. Worldwide 80% Lithium Ion Battery is made in China, including NMC and also LFP.

                  And most people think they will get a Fed rebate on their EV because that is what they are being told. But if you read the fine print a lot of people will be disappointed in the final cost.

                    You said the fact. But in the end, most people will buy and pay. Ordinary people can't play with the giants. That is history.

                      But with a bit of research, they can be better informed, less naive and maybe have a few less unrealized expectations with some due diligence and not believing everything they are told or read.

                        I am just saying that our present Fed Admin keeps pushing people to get an EV and state they can get a rebate but that info is mostly misleading unless you do the investigation.

                          Yes, I agree with you. You are right!

                            In the past it has been a federal tax credit and I never saw anywhere that the federal government called it a rebate. Many many uninformed people, including salespeople, have incorrectly called it a rebate.
                            I have not seen the details of the new federal plan but one source said it may take place at the point of sale. N that case it may resemble a rebate. I have an order for a new EV which is scheduled for sometime between November 2022 and January 2023. Depending on effective date and final price I may get an effective reduction in cost. Either way the value is there for me. By then I will have done the investigation and read the fine print.

                                I assume you are referring to battery manufacturing? Tesla currently manufactures batteries in Nevada and is doing a pilot run in Texas. Earlier vehicles did have batteries manufactured by others overseas, but that has changed since the Gigafactory was completed. Musk is a businessman, and Tesla is more vertically integrated than an other vehicle manufacturer. Check your facts before making statements or preceed your statements with the qualifier, "In my opinion,".
