The battery supply issue is one that has affected most of northern europe for the last few months, but the good news is that some Pylontech batteries are available, and things are calming down a bit. As of 18th November we can source Pylontech US2000 batteries, and US3000C batteries are expected to arrive in 4-6 weeks.
We are confirming availability of batteries before any order is confirmed, and will advise you if your batteries are available immediately or on back order.
