June 21, 20224 yr Hi I have mostly standardised my installs on Sunsynk inverters with Blue Nova batteries . I had a request from a customer to review the use of the Hubble as an option - they seem cheaper , can use the Sunsynk CAN bus natively , have a 10 year warranty and comparing the DU form Blue Nova similar capacities . Any comment would be appreciated as to support , issues , ease of install, how long have they been in the market , would you use them again , multiple battery setup etc. Thanks
June 21, 20224 yr They still use the NMC chemistry in the AM2 which is being phased out internationally due to the usage of cobalt,nickel and safety in regards to fires ,i would stick with Blue Nova as they use LFP cells .
June 21, 20224 yr I have 3 Hubble AM-2 and they are great, easy to install and does what is says on the box. Hubble support is also good. Will definitely use them again.

Are NMC cells also being phased out of Tesla car batteries?
June 21, 20224 yr Yes, they turned to LFP also. Phased out a while ago. The metals are becoming scarce.

So they have started using it in their short range Model 3s. AFAIK, all the rest is still NMC. The most notable recent news is LG moving away from NMC, while at the same time issuing a recall on many of their NMC batteries... NMC does have a shorter cycle life, but Hubble claims to under-charge the cells to 4.1V in order to extend the life. Unfortunately there is no long term test of the Hubbles to confirm how well they hold up.

Of the 100 or so Hubbles I have installed, I have had a cell issue on 2 batteries and a BMS issue on 1. All 3 were replaced by Hubble with no issues whatsoever.

June 22, 20224 yr Author Hi all Thanks for the replies , my take from this : Support ,mounting etc. probably similar . Only real difference is the chemical make up and then we into the NMC vs LFP debate . I can understand the case for the higher density for the use case of Electric Cars( I have a i3) and Cell Phones . You will find that in those cases also each cell is monitored and you have sophisticated BMS management in place . In the case of storage batteries you can reuse NMC as a storage battery as a second life option but for home installations where you are sometime compromised as to where you have to install batteries ( no dedicated battery room etc) I would opt for the inherent safer chemistry of LFP . I was involved in the review of a Battery Fire in Nelspruit - It was installed in a dedicated battery inverter utility room and substantial damage to the room and the garage was done - if that was in the house it could have been deadly as the wires that burned cut the power to the safety door and the people was locked in( and yes that they only found out with the fire ). I will provide the feedback to the customer and she can make the call . Thanks
