Peterlove11: This would give him 452.4v, still above 450v |

Penuelseun: Have checked the datasheet n even the 470watt ja solar is 11.53amps ISc n 50.31v at VOC... abeg bro, do u have details of a trusted ja solar dealers |

Xanderone: I don't have any issues against him except for his failure to respond to WhatsApp messages. At the time I made my own complaint over 3 weeks ago, he was online but didn't read the messages or maybe he read it but turned off read receipt. Beyond that, a customer called to complain about your product. The modest thing to do is to follow up but nothing so far. If getting across to him is proving to be a problem, I can't just blindly send a package to Jos hoping for the best outcome. Imagine your own case. I'll open the battery myself and see if I can get a replacement cell. 1 Like |

Honestly, the back & forth logistics is frustrating, the money for it, for which I didn't even charge the owner of the battery, plus the stress to haul that heavy pack (back & forth). It's in a metal box. My solace is in d fact dat d stack I gave to her as stop gap is working so well she has no single complain. I suspect she may be unwilling to let go off of it if and when her own pack is restored. Now I'm beginning to wonder if it isn't Li-ion that is in that stuff cos the metal box looks like the picture of the one op ed. One thing that stands out is that every other pack I'd gotten from him are in plastic case, but only this one was packed in metal case. I'd have opened it a long time ago, but no time, plus I didn't wanna do anything that'll void his warranty on it. But d way I'm looking at it at the corner where I kept it, I might be tempted to unsheathe the screwdriver one of these days. durodee: |

mctfopt: You can even do 9x 585w which puts you at about 5300. Like that guy said, you'll not get STC ratings; rather NOCT. See attached chart and do your maths 1 Like 1 Share |

RFQ!! For our battery couplers in the house. I would like to get from those who are interested in coupling a bespoke lithium battery for a small project. Information and specs will be shared about it to those interested. Please enter my DM if interested. |

xtremeidea: No it is not universal if that's what you asked. Every Vendor has a Unique Module ID on this device that must be recognized by the Communication and Data Board inside the Inverter. If not, the device will simply get powered up but will not communicate nor give you any data reading from the inverter. |
jonescosmos(m): 8:19am On May 05, 2024 |
ewizard1: No sir, you are wrong on this one. Except it's a quack, manufacturers will not cross a bar on top of opposite battery terminals carrying high currents. they cross it between the terminals clamping the cells in equal halves. There ought to have been two bars in that pack, one holding each cell rows respectively. And the bars will act as rails for cells cable management. That's how we do it. |

xtremeidea: Sure it works excellently but not sure it is compatible with all products from other OEMs. You can monitor and control the inverter remotely with it. One draw back is that the monitoring page takes a few minutes to update so its not real time. But the command control is immediately. This is the web interface http://www.dessmonitor.com/?#/generalNew/home The attached picture is a typical day. After battery was 100% the PVs stopped harvesting and dumped the excess into a Lagos lagoon ![]() The second is the web view of my operation today. Grid breaker has been off since yesterday morning that is why battery drained to about 29% and is chargig it back up.

mctfopt: What should be of concern to you is the system voltage. JUST DON'T EXCEED YOUR SYSTEM MAX VOLATGE Your System can only draw a max of 10A even if you a have 15A total assembly but make sure your MPPT Max Voltage at STC is not exceeded. Eg. Say you have 450W 12A @ 37.5V s And your MPPT spec says: 450V @ 10A, It's very safe to have 10 of this in series which will give 375V @ 12A STC, So your MPPT will draw it's 10A complete and the excess will not be of any harm to it. But in all this, NOTC will reduce these readings for you. At least in Nigeria anyway. 1 Like |

DaniellaDokubo: Not entirely true sir, It stopped harvesting because your applied load is not drawing the Solar Energy after your battery gets full. Thus is why you have to do a little trick on setup using your [b]Dry s or SmartLoad [/b]if your inverter has it, So that you can power up things like ACs, Fridges, etc once your battery get 100% SOC. by doing so, they draw or harvest the solar energy that your Inverter could have thrown into Lagos Lagoon. but you must not over power your KWp or else they will be steeling your battery energy . |
DaniellaDokubo(f): 8:59am On May 05, 2024 |
jonescosmos: The residual load of 300W is my load when no one is at home it is basically freezer and fridge. Yes my inverter has dry s which I connected to a or that pulls out the freezer if I need to remotely. I also plan to add my AC next when I have the chance too. For my battery it all depends on the setting I choose. Even if it takes from the battery during cloud cover it restores it back up when sun comes back. |
DaniellaDokubo(f): 9:12am On May 05, 2024 |
mctfopt: From experience your s wont get you much of what is on the name plate wattage. I use imported s and my data logger has showed the s could get only a paltry 60% of its designed capacity. This is after observing the production for a period of time on daily basis. Way forward is to oversize your PV system but not the Voc as that is the only thing that is always higher than the name plate value when it is in use. Don't waste your money on any anything. 1 Like 1 Share |

jonescosmos: I understand all these, the plan is to put as much PV s as I can per growatt. I'm sort of annoyed I can only do less than 5kw when said inverter can do 6kw. Growatt has a maximum PV input current of 22A. I'm unhappy I can't run parallel as most s above 400w has Isc more than 11A making parallel impossible. The other alternative is to get lower capacity PVs, the space is very limited. |
mctfopt: 9:29am On May 05, 2024 |
DaniellaDokubo: Sorry, I guess you don't understand my predicament. I wanted to put as much PV as I can possibly can on one Growatt |

Isc or Imp? Cause but are totally different. Edrizz: |

What's the max pv power and VOC of the inverter? mctfopt: |
ewizard1: 9:57am On May 05, 2024 |
jonescosmos:Would share images of cell clamping when I get them. |
mctfopt: 9:57am On May 05, 2024 |
Ferdiwar: MPPT range is 120-430v Maximum PV wattage = 6000w Maximum PV input current = 22A |
Oshomo12(m): 10:05am On May 05, 2024 |
mctfopt: In the manual, did they work with lower capacity s? I don't want to assume they never intended you getting near that 6000w in the first instance. 1 Like |
Ferdiwar: 10:41am On May 05, 2024 |
Please I need your input on Deye inverter specs. Mine is the 5kw with 2 MPPTs, the specs reads; Max PV input power of 6500w. PV input voltage 370vdc (125vdc - 500vdc). PV input current 13Adc + 13Adc. Now I understand that the input current is 13A for both MPPTs but I don't know if same is the case for the input voltage. My question is "is the 370v (125v - 500v) for each of the MPPTs or a combined voltage for both MPPTs"? I want to increase my s wants to know if I can still add to already existing setup or make provision for an external CC. jonescosmos: |
