Hubble Energy providce excellent support for their products.

My solar instattion was activated in Jan 2022 and includes 4 x AM2 Hubble Energy batteries. On two occassions since then, I have noted odd data values and contacted Hubble Support. Fortubnately my installation includes their RIOT connection and they are able to access my batteries for remote analysis. In both cases they requested me sending batteries tp them for warrantee service/repair. They commmunicate well regarding the staatus of their activitties and when they have completed the repairs/service. Other than courier charges, there have been no other costs related to this.
