Paired this Hubble AM-2 with my existing Sunsynk inverter and the setup was completely plug and play. The battery management system is solid and it has been running daily charge cycles for five months without a single issue. The LiFePO4 chemistry gives me confidence it will last well beyond the warranty period. Great build quality.

Added two Hubble AM-2 units to expand my storage and the difference in overnight capacity is significant. We now get through the longest Stage 6 blocks with power to spare. PowerVault sorted me out with a competitive price and fast shipping to Pretoria East. Solid product backed by a solid warranty.

Added the Hubble AM-2 to my existing Victron system and it integrated without any drama. The battery has been cycling every single day since August and capacity is holding perfectly. Bought from PowerVault because their price was the best I found nationally. Shipping to Pietermaritzburg was quick and the unit was very well protected in transit.

Expanding our existing solar setup and chose the Hubble AM-2 on the recommendation of our installer. The battery arrived quickly to Louis Trichardt which honestly surprised me given how remote we are. Setup was easy and our installer said the build quality was noticeably better than a battery we had bought from a different supplier the year before. Happy with everything.
