NiyiOmoIyunade: 1: yes, there is a BMS bundled with the battery internally... 2: the HVD is 14.6v as I have always monitor that with a volt meter even though the charger has an indicator that turn to green from red when the battery reaches 14.6 3: I have not measured the cells before as they are all welded together in the pack (bunch of cylindrical lifepo4 batteries) |

Re: Solar Energy, A Complement To FTA by odimbannamdi(m): 2:59pm On Mar 04, 2023 |
Smartwoods: Hello bro... To help you get prompt and effective advise from experienced folks here, consider mentioning the brand of the Hybrid inverter (and the CC technology [MPPT or PWM]), batteries and panels (I recognize that it may be diffucult to get a picture of the nameplate showing the specs since they are already mounted). Better still, send current pics of the harvest as shown on the inverter screen Also state the connection configuration of the panels and confirm whether the batteries are connected in a 12v (parallel) or 24v (series) connection 1 Like |

Put them in parallel. U can use branch connector for that instead of cutting ur mc4 connector. If ur hybrid cc is pwm. It will b better if u can get mppt cause there will b some wasted energy on pwm Smartwoods: |

odimbannamdi: Thank you The Inverter is a 3kva 24V Srne Hybrid Inverter with VOC of 100V The panels are 450 Watts by 3 panels and they are already mounted The batteries are (2) 12V 200a batteries and I'm not am expert so I wouldn't know if they were connected in series or parallel but I believe it should be in series since the inverter is a 24V inverter system The MPPT is a 30-85Vdc with a Max input current of 40A |

Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 8:03am On Mar 05, 2023 |
CC OjeySky. He is a strong and highly anointed Deye apostle and fanboy! Technical note - for comms between these inverters and battery people typically emulate the Pylontech protocol on CAN - this is not always desirable esp as Pylons are 15S and setting up comms on this basis may lockout certain other critical battery parameters. It may be more prudent to pass only battery SoC to the inverter to drive LVD and stats but set your own charge voltage parameters custom as you would have done for any other battery.

My Oga TrippleDots! I hail una o 1. I guess the Fronius is on the AC input side of the Victron Multi/Quattro? Please confirm What PV related assistants are you running on the Multi/Quattro to manage energy flow. Are you using the default frequency shift thresholds or more aggressive/conservative ones. 2. If the actual loads are within 10kw per phase where you have 15kva inverters you should look to your wiring on the load side - the most frequent cause of the generic 'overload' light flashing is actually faulty wiring. You are looking for all neutral wires for the inverter loads properly moved to an isolated inverter load bus/DB and all neutral wires for non inverter loads moved to the mains DB. Any crisscross of neutrals between mains and inverter side causes these kinds of issues. If you are pressed for time or want the easy way out, move the inverter supply to AC out 2 and set a suitable assistant to run ACOut2 off battery and prevent overloads. See sample assistant setup below - the red circled (de)activates AC Out from battery based on battery voltage - you could also use SoC or other parameter The blue circled abi na rectangled protects the inverter from an overload situation e.g in the case below for my house disconnect AC out 2 if loads higher than 9,500 watts for 60 seconds and reconnect or activate AC out 2 if loads under 9,500watts for 200 seconds. Two things are important here - 1. The assistant logic is inverse so that START means STOP since the control is OPEN RELAY TO START..... 2. The backoff time for the AC contactor is tres importante - Victron backend dev strongly discourages the relay cycling rapidly ON/OFF several times a minute - it would stick shut and need visit to service center hence I give a mandatory 3 minutes (200 seconds) rest and cool off period if ever the inverter overloads and a 60 seconds of sustained high load before the inverter trips the AC out to allow large transients to pass with no trouble.

For that second question, I have made the assumption that all issues like phase rotation e.t.c were already sorted since you said things mostly work. To quickly find a 'common/crossed neutrals' issue I usually employ a test lamp. With mains available, switch off the inverter AC input breaker so that all supply to inverter loads is coming from battery. With inverter AC input breaker switched off, apply test lamp between inverter AC out live and mains neutral. If the test lamp lights up then you have an inverter load whose neutral is still on the mains DB. Drop wires off the mains neutral bus until you isolate the offending neutral and relocate it to inverter side - there may be more than one neutral wire causing this problem. Now repeat the test in reverse - disconnect AC input to inverter and apply test lamp between mains live and inverter neutral bus - if the test lamp lights up, there are mains loads whose neutrals are on the inverter side. For this case decide where the loads really should be and handle appropriately. This test needs an incandescent bulb, a clear schedule for the day and plenty of patience to do in a complex miswiring situation. If you can get the electrician who (mis)wired the building to attend that would be very good too - they usually know all the shortcuts they took and (mis)wiring they did to cause all these problems, just be nice and kind to them during the process and things should typically work out well.

Can someone enlighten me please. - What are the advantages of factory assembled lithium batteries over the locally assembled lithium batteries of same capacity and vice versa? - Which is more durable and efficient? - For a 5kva system, what capacity of lithium battery will be required? Also for a 3.5kva system. Thank you. |
