I'm considering investing in EcoFlow Delta Pro 3 systems priced at $4199, which would provide 8kW and 240V to power my small farm. My budget is around $3000, but I'm willing to stretch a little for this setup. I'm also looking into purchasing two 400W bifacial panels for about $600 and a 4000W inverter for $600-$900, plus around $2000 for batteries, cables, and an MPPT controller. Do you think the price for the Delta Pro systems is reasonable, or should I consider parting things out for a better deal?

Honestly, assembling your own system could lead to savings. I'd recommend aiming for more panel capacity—at least 1600W with around 4 panels to start. I found Canadian Solar panels going for $165 each, which is a solid deal! You might save a ton if you shop around.
I recently went for a Jackery 5000 Plus system that has around 5kWh of capacity. Honestly, it’s a fantastic option if your power needs are not too high. For my investment, I found it advantageous since going the component route made sense only when you go beyond 10kWh. What's your daily power requirement?
Your panel sizes seem a bit low. I just set up a 3.7kW PV system with a 5kW inverter and 10kWh batteries. It keeps my system plentiful on sunny days, but cloudy ones can be tricky. This setup could really thrive on a farm where you can avoid shade.
If you're looking at $4.2k for two Delta Pro 3 units, consider exploring options like the EG4 6000XP paired with 2-3 server rack batteries instead. That might give you some more flexibility and power for your farm without breaking the bank.
One downside to all-in-one systems like the EcoFlow is that if something fails, it's all or nothing; you can't swap parts out. I've seen inverters fail before batteries have finished their lifespan, which could leave you in a tough spot. Just something to think about!
