App-controlled charge limits make it easy to leave the battery near a storage-friendly level before storms or trips.

Long-term storage requires periodic partial charging, but reviewers consider the routine straightforward and not burdensome.

Cons: MPPT controller performance, battery expandability
Long-term storage is simple, but Anker recommends periodically topping up the battery rather than leaving it untouched indefinitely.
