Any guides for installing these with existing Rooftop Solar + battery config (like Franklin/ Tesla Powerwall3)? I think the 15Kw Franklin wont be enough for my day to day usage.

Do you know if these are actually acceptable as a UPS for computers/servers? Looks like River 3 Plus and Delta 3 Plus are not. This post details the issues with using them instead of a UPS: https://www.reddit.com/r/Ecoflow_...lus_delta/
I'll give a contrary take to SeriousLlama: I've been using a Delta 3 Pro as a backup to my server and it's been rock-solid. The Pro and Ultra are rated as UPS-capable, while the River and Plus are not. The switchover time is under 10ms. I heard about the case SeriousLlama mentioned, and it sounds like the issue was with the home power supply rather than the Delta unit itself. The unit does not do power conditioning of line power when it's in pass-through mode, but the power in battery mode is clean. If you're concerned about dirty grid power, you can add a power conditioner, but a modern computer PSU is capable of handling quite a bit at the cost of some efficiency and heat.

As for leveling cells on a lithium-iron battery: you DO NOT DO THIS BY DRAINING THE BATTERY. You charge it to 100% and leave it at that level every couple months for a while. Most of the time, it should be at 60-80% for longevity. Don't take it from me though, look up DIY Solar with Will Prowse's video "The Rules of LiFePO4".

are you certain about that? is ecoflow lying?

10 ms Switch-Over UPS Protection. The DELTA 3 Plus functions as a true UPS with a 10 ms switch-over time, ideal for NAS, servers, POS systems, and critical backups, ensuring no data loss from unexpected shutdowns.

Does it qualify for the tax rebate? Since it's just battery itself

Do they ask for proof of installation? It's simply plugged into an appliance..not sure how much more proof they need to be considered as installation?
just got my 30% tax credit a week after filing for 2024, for the dpu that i bought in 2024. no proof was required unless of course they audit you later, then of course have your receipt copy. i will claim same credit for just installed inlet & interlock on next years taxes, along with my 2nd extra battery (bought from hd today) which qualifies too for 2025 taxes, since it's another 3k kwh and above watt hour (wh) per year that you can claim. see thread below discussing the topic.

Perhaps the Plus is now, I don't believe it was when I bought it.
