I installed 3Hubble AM-2 batteries together with 3 Sunsynk 5-5k in parallel. All works well. I would like to add one more battery. I hear that the newer AM2’s have prismatic cells which are not compatible with my 4 year old batteries. Is this correct - do I have to source a different battery?

Done

Been monitoring my soc last few days and the process seems to have worked. Well, getting 99 % soc which I am quite happy with. Thanks for the advice everyone.

Yes, did it today and…….. got 100% soc by early afternoon. Let’s see what tomorrow brings.

So a big sunshiny day in East London, and I still cannot get beyond a 71% Soc. It could be me, it could be my 2 month old system or just plain bad settings. help! it’s a Sunsynk 5.5 x 2 paralleled system connected to 3 Hubble batteries. Plenty of power available from 24 JB panels. settings are as below: Hi, my system is 2 Suynsynk 5.5kw inverters in parellel feeding 3 Hubble AM 2 5.5kw batteries. I have 12 455w JA panels facing East and a further 12 JA 455w panels facing west. The LIBMS screen at1pm today in full sunshine is below. the battery does not discharge during the day. It reaches the 71% in the morning and does not increase. Monitoring is the Synsynk module. My goal is primarily to save electricity costs and secondary to beat load shedding. Thanks for responses from HiTech, Scorp007, YellowTapemeasure, and system32.

In the midst of load shedding I now have no power. Apparently I have 59% battery power according to the inverter. Clearly I have a settings problem. advice on settings please!

Been using the Blue Nova for a couple of months now with no problems for my gate.

Ha Ha. Well said Greenfields.

Thanks P1000.

Super excited as my new system is in process of being installed. 23 Ja Solar 455w panels feeding through 3 strings to 3 Sunsynk 5kw hybrid inverters in parallel. This will power 3 Hubble 5.5kw batteries. Yay! I exclaimed to my installer. I will soon be out of the clutches of big bad Eskom. Not so old man, said my installer shaking his head sagely. Your Hubbles have not yet arrived. Your system cannot power your home if you do not have batteries and the power from Buffalo City Munkeypality goes down. You will only have power from your panels feeding your home if you either have batteries ( which haven’t arrived!) or BCM is feeding your home from the grid. When the grid goes down, your inverters will shut down and all that power being generated from your panels will be wasted. What! I exclaimed. Surely not! So, dear Forum members, is he correct? Is there a way around this debacle? Looking forward to some wise advice.

Hi Peter V, Im also in EL, Bonnie Doon, and am considering installing a pv system with battery backup. Would you mind sharing whom you used for your system and whether they met your expectations? Thanks, Brian K

Thanks, Gnome, most informative.

Would 3x the new Growatt SPF5000 ES 5 kw inverter at around R12000 each be a good alternative?

Hi Experts! looking to set up a system in East London for a large house. I have a 3 phase system. My question: if I get a 3 phase inverter, say 15kw, connected to one Lithium battery, does it mean that each phase can only draw up to 5kw or could it be, say, 3kw, 10kw and 2kw at the same time? Will want to feedback to the Grid as well. Thank you.
