Inverters/chargers lifeP04 batteries

Do big inverters (3000 watt cont..) damage lithium batteries in the same way they damage lead acid batteries when run at lower outputs like not much in the night.
And if I were to buy a 3000 watt inverter/charger in which you could set the charge output to 10amps the max for my lithium battery bank  would it not damage the lithium batteries even though it did not have s lithium charging profile and I would envisage maybe finishing charge with lithium charger to bring the bank to full charge.
Thank You.

    I'm not sure what effect you are talking about, a 3kw inverter damaging batteries overnight with low power ?

    Can you be thinking of the internal losses poorly made inverters have, just being turned on, consuming 90 watts idle ?  That will flatten a good battery, regardless of it's chemistry.

    Ii am talking about larger inverters being run every night or any other time for long periods at say 11% load significantly shortening the length of time a lead acid battery will last it's lifespan in terms of years.

    Getting close to 30 years offgrid. Never have had the word "damage" associated with that we do. Early on we had 4KW Trace inverters and now they are all 6.8KW. Hoping to get 15 years out of lithium and 10 years out of lead acid for my clients. Probably will.

    Inverters always run, they never go off.  

    Might be missing your point, explain it differently.
