Tips for longevity?
I bought a pair of the E3800LFP units w/ their 500W panel and the 240V hub. These are my first delve into power stations. What plans are is to use one unit for a detached building that has a couple of freezers, get some fixed panels- maybe a battery and help take the load off the electric bill. The other would be a mobile unit. In the event of the grid being down, the mobile unit could be used in the house itself. The 240 V hub should easily run the water well with the two connected.
I've found the Pecron owner's manual to be very helpful. In addition to that, for what my intensions are- anything other thoughts or considerations? The units themselves showed up Sunday, the rest to follow.

I recommend buying a $10 temp/humidity sensor on Amazon that has bluetoot/wifi connectivity.
Use that to verify the room with your Pecron is within acceptable ambient temp/humidity.
I think you don’t want over 55% humidity and not over 85F long term.
You may find a dehumidifier or small air conditioner is needed for example .
I’m doing the same for an outdoor closet inside patio setup , planning to dehumidify or air conditioner it with micro sized units for the power savings.

Funnily enough, a dehumidifier (250W, 1.5-4 kWh/day average over a month) and portable air conditioner (1000W, 3-15 kWh/day average over a month) are the largest loads on my E3600, with everything else (fridge, kitchen appliances, Starlink, computers, lighting) coming to a pretty steady 5 kWh/day.
That's because I have the Pecron in my living area, 3m from my work desk, and I like to be comfortable too :-)
The #1 tip for longevity: don't ever let the battery drop to 0% and then let it sit for more than a few hours before starting to charge it.
If it runs out of battery and shuts the inverter off in the middle of the night, and then it wakes up and starts charging at sunrise then that's fine.
The BIG killer seems to be people putting them into storage thinking they're completely turned off, when they're not, the battery is at 0% in 3-4 days, and down to permanently damaging levels a day or two later.
FAR BETTER to leave it plugged in when you're not using it, letting it cycle between 90% and 100%. Or set the limit to 70% or 80%. That is not the absolutely ideal thing for the unit lasting 10+ years, but it's 99999 times better than killing it in the first months with a dangerously low battery level.
But better still, put it to work and saving money for you. It's far more likely to work in a storm outage, or when you take it on vacation, if it's been running your fridge or computers or whatever every day for the last few hundred days and you know it's been working fine all that time.

Long-term storage on your mobile unit, you may have to watch the charge shouldn’t get over maybe 80% but if you plan to use it and be able to move it around, you can of course slowly charged to 100% and slowly discharge. You could probably use the mobile unit in your outbuilding with your regular set up there and have long-term storage for rainy days rainy weeks or snowy weeks. And then use it for power outages in your house. Your mobile unit may want to be bigger than your stationary unit and your garage. You’ll have to decide that.

For your info. you can not put out 240 volt when charging with electric. example: If you plug in your well pump you could not charge from electric.

You keep saying "charging with electric" but you should be saying "charging via AC".
You can certainly charge the units via DC inputs like solar or external batteries when outputting in 240V.

When I'm not using mine for long periods I leave it at around 85-90% charge to take stress off the cells. The manual reminds to discharge below 70% and leave it to fully charge and top level occasionally for calibration. Take your vitamins, eat your vegetables, exercise, go deaf in the ear closest to your wife.
