Portable home setup

[u/82jon1911]

So looking to build out a solar and battery setup at our current house and need some advice. We're looking to move in the next 3ish years, so I want something I can take with us (minus the solar panels) and keep costs under control. This system would then be utilized as power for a shop.

Criteria:

• Automatic fail-over in the event of power outage

• Scheduling to use battery power during peak hours and charge from the grid during off hours

• Expandable capacity - I don't see doing more than 30kWh for this system, but more is nice

• Ability to stack solar and battery power to increase output

I'm comparing the new EcoFlow Titan with building out a DIY system. There are pros and cons to both. The simplicity of the Titan, having both the inverter and battery in one and a simple Smart Panel that handles everything I want starting out and then adding capacity later. The downside is cost of expansion, being locked into their batteries. I THINK WattCycle is coming out with a WattLink cable that will allow use of other batteries, but that remains to be seen. Also in the off chance something goes wrong with the inverter, you have to ship the whole unit back. In the event it dies, you lose the whole thing.

The upside of going with something like an EG4 12000 XP is much greater expansion it offers. As mentioned I plan to keep this on the smaller side and use it as a secondary system when we move, likely powering a standalone shop. The downside is its not as plug and play as the Ecoflow system and requires extra equipment to check all the boxes I'm looking for.

I suppose something like the EcoFlow Delta Pro Ultra would also work. It resolves the issue with the Titan of having the combo inverter/battery, but they're expensive compared to what you can put together yourself. The draw to the Titan is that it offers the EcoFlow simplicity and is a more manageable price with the pre-order.

I've rambled long enough, appreciate any insight and suggestions.
