NiyiOmoIyunade: If you have 2P DC breaker why not disconnect both + ve and -Ve- The way I normally do it is to use DC breaker immediately after the battery so it can safely switch off all inverter, charge controller and the shunt |

Thanks @NiyiOmoIyunade for the great help. I used Microsoft Visio 2010 for the design. The meter came with attached cable in the picture below. Guess is the one you are talking about. [img][/img] NiyiOmoIyunade:

Ok thanks @pranil. Is it the -Ve from the inverter that would pass through the breaker or the the -Ve (jumper cable) that would pass through the breaker B? pranil: |

sinistrian:The Fangpusun are clones of the Victron in this regard. However, after the initial minutes of hunting the grid, it seems to constantly do sweeps. Data extrapolated from my 5-day old Victron BlueSolar MPPT 150/70 (VE.CAN model) |

MAboyarin: That function is best left on the "default" mode(13.7v/27.4v).....its got to do with charge voltage, the customized mode involves some pcb component tweaking which alters it to some voltage values depending on the level of tweaking. |

NiyiOmoIyunade: Thanks so much for the response. Truly the insights and the advice you all give is truly priceless. Will probably continue alternating batteries for another week or two before I "parallel" them together and will contact you soon on the desulphators. Thanks again. |

can someone educate me on the max instantenous current draw from a batt bank, without damaging the batt. eg my 48v 200ah bank, going by 10hr discharge rate, can I assume 20amps is the max draw, thus max allowable instantenous load is 20a x 48v = 1kw load? |

Yes. The batteries wont be damaged if the rate of discharge is exceeded, only its effective capacity will be reduced (Peukert's law) Reprobate: |
Re: Solar Energy, A Complement To FTA by Chuckdee(m): 9:56am On Jun 12, 2018 |
Barezzi: Hi Barezzi, Please how did you achieve using the grid to power your AC load w/out the inverter charging the batteries at the same time? I use a Magnum Inverter and haven't been able to see a setting that will allow me to turn off the charger completely (can only regulate the charging rate) I would ideally want an automated arrangement that would allow grid power to pass thru the inverter when available from 6pm to midnight w/out the inverter charging my batteries with that grid power |
Re: Solar Energy, A Complement To FTA by Barezzi(m): 10:05am On Jun 12, 2018 |
I sold my premium Magnum inverter and bought a Gennex hybrid. It has settings that allow intentional islanding and grid passthru with the charger off. I have forgotten, but i think the magnum allows you to set the charge current to zero. Chuckdee: |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 10:43am On Jun 12, 2018 |
chuckdee, if you're using the magnum ms4348pe with the advanced remote me-arc50, there is a button for turning off the charger completely. Also, you can program the charger to cut-off and cut-in at certain times of the day, say from 6am to 6pm. This among many options make the magnum a very robust beast of an inverter.

Re: Solar Energy, A Complement To FTA by godspeed: 1:06pm On Jun 12, 2018 |
godspeed: Hello house So much confusion everywhere ooo! So I got a professional installer to take a look at my set up and confirm why the battery is not charging. First thing he said is that instead of using 2 250watts panels, I should have gone for 4 150 watts panels, because this according to him, gives me more amperage - 8 amps each translating to 32 amps. He said the battery (220 ah) requires 22 amps to charge while I can use the excess amps to power my appliances. He claims the 2 panels I have presently generates max of 12 amps which he claims can never charge the battery full. He also tested the voltage coming thru the CC and got ~36 volts, this he said is too much for the CC as it's designed for 12-24 volts and claims the excess volts is not healthy for the CC and it's preventing it from working optimally. I had him speak with my installer and he said why he used 250 watts is to get 24 volts which can be converted to more current to charge the battery. Both of them just left me confused with their technical jargons but both agree I need to change theCC to MPPT. When the professional guy says I need to add one more 250 watts panel to be able to get a full charge on the battery daily, my installer claims changing the CC to MPPT will fix the problem as it will convert excess volts to current which is sufficient to charge the battery full. So house, I'm really so confused |

ebocoms: If you send the visio native file to me I can redraw but basically - battery -ve from the battery to DC breaker and then toshunt battery side same with +VE - from Battery +ve to breaker first and then to inverters, CC + VE ETC Also note DC breakers can have polarity and the side marked with +Ve symbol should be on the battery side ( side with the highest voltage of power flow possible) |
Re: Solar Energy, A Complement To FTA by pranil(m): 4:20pm On Jun 12, 2018 |
godspeed: Stop thinking of Wattage, voltages etc, PV panels are not generators. They are you diesel tanks Inverter is Generator while PV + Battery provides the energy to run the inverter ( Generator). A good installer then should match the correct voltages, currents etc based on the products used. Most important to think is Total energy required in the day The minimum you should target is in KWH is atleast 50 % of Battery capacity ( 2.4 Kwh for you I guess ) + amount of energy used during the sunny period in the day What you need a Quality MPPT CC preferably which can handle 100 V or Above input ( Voc) then you can connect panels in series That way you reduce the cabling loss and the CC will wake up earlier in the morning and go to sleep late maximizing the usage of the 500 watt you should get typically 1.5 2 KWH on Average yield from 500 Watt panels with correct Cc and installation - The Yield ( energy is important ) not the wattages, If you are using inverter/battery in afternoon you will have to calculate how many units you typically use in afternoon and increase the panel size to address that. in your case you have the possibility of to 250 x 2 ( 2 in series) or 250 x 4( 2 series, 2 strings parallel) or 250 x 3 ( 3 in parallel or series depending on CC) |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 4:22pm On Jun 12, 2018 |
He is not a professional installer! get an mppt cc and connect those two panels in series and you are good. better still patronise installer from this forum and have rest of mind. godspeed: 3 Likes |

Re: Solar Energy, A Complement To FTA by Saipro(m): 5:53pm On Jun 12, 2018 |
Reprobate: Pretty risky assumption and could lead to early battery failure. Inverter and cabling inefficiencies usually total a minimum of 15% of the power (translated as 85% efficiency). Your 20A pragmatically becomes 17A (assuming C/10 discharge). Most FLA batteries won't safely take beyond C/8 as discharge (AGM often can tolerate higher). Assuming the stress limit of C/8, that's 21A (though I see no point in pushing batteries to their limits unless absolutely necessary). Then there's the issue of variable inverter self-consumption ... |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 6:01pm On Jun 12, 2018 |
Connecting in series will ensure ur system wakes up on time and sleeps late wrt sun rise and sunset however since your system is 12v and most 250w panels are 35V Voc it means that connecting in parallel is fine but you need to get an mppt controller. This has the ability to convert excess voltage to current just to put it simply. Contact me for this controller... See my signature godspeed: |
