conradl Posted February 7, 2022 Share Posted February 7, 2022 So, my install was done yesterday Summary: 1 x 5kW Sunsynk Inverter and 14 x 455W JA Solar panels 2 x Hubble AM2 batteries (another one planned for) Installation took appx 6 hours and I'm very happy with attention to detail that team applied, to the DB as well as what's "hidden" the trunking and main DB. Lessons learnt (if anyone else ever encounters a similar situation): We had issues with the inverter "tripping" with a F20 (overcurrent) error intermittently. This happened on and off without a definite idea of why it was happening. No issues at night and the house was running off the batteries fine through the night. This morning, Leshen checked on the system and at around 10am the error started popping up non-stop. The inverter would trip (power ironically stayed on in the house), and alarm for 2/3 minutes before going back to normal. it would run alright from 1minute - 10minutes and trip with the same error. Leshen came over and did some investigation. Finally, there is only one SPD installed in the DB with both Negative poles of the PV string connected to one SPD. Leshen then connected each String to its own SPD, and it's solved the problem (touch wood)! I want to thank @Leshen and his team again. The Customer service really is great! Also thank you to Steve of PowerStore for supplying the equipment. Jacques Ester, Antonio de Sa, Yellow Measure and 6 others 9 Quote Link to comment Share on other sites More sharing options...

Saliegh Posted June 18, 2023 Share Posted June 18, 2023 What thickness is the wire between the inverter and batteries? Quote Link to comment Share on other sites More sharing options...

I am trying to understand why, what looks to be a +200amp battery fuse disconnector, would be installed, when the 5kw has a max charge/discharge of 100amp, and the Hubble AM2 as a max of 115amp charge/discharge rate (old one has 100amp max). The only reason I can think is that you upgrade to an inverter that can handle a higher DC charging rate. Is that the reason? Quote Link to comment Share on other sites More sharing options...
