JHBPower

Thank you! That's a huge help. Last night I already changed to AGM setting per the advice from a powerforum post on another thread. I have not however drained the battery and then let it recharge with the AGM setting. I'll try that today. And of interest, with the AGM setting, did Hubble recommemd to set the float voltage at 53v and Bulk/Equalisation at 53.6V as per the AM2 manual ? Or did they recommend 53.6V for float and also 53.6V for Bulk/Equalisation. I'm surprised that 53.6V is not used as float and bulk/Equalisation setting, given that the BMS of the AM2 lithium does all the "thinking". I'd expect the BMS would want a constant supply voltage input, and then it would manage the cells as it sees fit.

Hmmmmmmmh...........I have the same problem except that I'm stuck on 63% SOC. I've tried everything in this thread except updating firmware. I see Swazz99JHB says that Hubble JHB suggested different settings for the inverter compared to what is on the hubble website. Does anyone know what those settings are? And do they make any difference.

Regarding your municipal meter that keeps tripping.........Keith from Sunsynk in a you tube video explains that there is a minimum consumption setting that can be set in the sunsynk to avoid accidental feedback into the grid which trips some municipal meters. So for example; if you set that value at 50watt and you are using a minimum of 250w, then you will always pull a steady 50w from municipality, and when there is a sudden change of load on your side you might drop for a split second to only pulling 10watt from municipality, which prevents the meter tripping if it had instead gone to minus 40w with no 50w min setting.

Hi All, Just introducing myself. Very useful forum this! Thanks to all the great contributors who have shared so much knowledge and brought me to this point. I've purchased a Sunsynk 5kW inverter and a Hubble AM2 through the powerforum shop. In the last weekend I overhauled my main DB. This weekend I'm installing the battery and inverter. And I'll then be hooking up with Leshen to commission the battery and inverter so that my warranties hold. Then next step will be PV after i fix some issues on my rooof. Wish me luck.

The concept of geysers in series is an excellent one. My thinking is to use excess PV solar during the day to heat the first geyser. First geyser then feeds the second geyser. Second geyser can then have a smaller element, say 1kw or 2kw for a 150L instead of 3kW and take power from inverter/battery combo. Given that my hot water heating consumes about 30% of daily electricity then using excess PV solar to heat the first geyser is an alternative to adding more battery capacity. Geysers are cheaper than batteries. At this stage I've not researched the best value for money methodology to feed excess solar into the geyser though.
