Hi Permies!

Sorry if this question is in the wrong forum, let me know if it is!

Jackery was having a BIG sale, so I just got a jackery 3000 with 2, 200 watt panels.

The info says that the battery is good for 2000 cycles, that seems fairly normal to me.

My question is this: Is there a way to power stuff using only the panels? For example, if the generator is 100% charged, and the panels are attached, and I'm using power from the system, am I doing that without cycling the battery?

It would be nice to take advantage of the panels without degrading the battery...

If your batteries are 100% full, and your panels are connected and producing more amperage than your requirements, then you are sipping from a full cup and not cycling the batteries.
I had to look up Jackery, and I did not see a 3000 model but I'm sure it is similar to the ones  I did see.

Bert,

Thomas is absolutely correct.  If your batteries are topped, connected to the solar panels and you are drawing less energy than the panels are producing then there is essentially no effect on your batteries.

It is worth noting that the 2000 cycle life is typically as a charge from 20% to 80% full.  If you are doing charges that are less than that then the effect on the battery is less that the standardized full charge, though the effect may not be perfectly linear.  The reality is that 2000 cycles is a LOT of cycles (about 5.5 years assuming one standardized cycle per day) and even then, that does not mean that the batteries are non-functional, but rather do not achieve the full charge like they did so when new.  I believe that at the end of the 2000 standardized cycles, the batteries will still charge to about 80% full.  All of this assumes that these are Lithium Iron Phosphate batteries which is an increasingly common battery chemistry in these types of units.

Hope this helps,

Eric

Thanks folks, this makes sense
