Good evening everyone, please have anyone here got links to a local RE seller who deals in flexible solar panel? am looking to get a few for my wacky lassie 16' fishing canoe have got in the pipeline. |

Namzy: That strict range of different VoCs for different voltage systems put some question mark on the efficiency. It may raise suspicion that the efficiency at all VoCs viz-a-viz the voltage system may not have a linear relationship in efficiency. Energy may likely be wasted if one goes a higher VoC that that recommended for a particular voltage system. If not for that downside and maybe a few more that may be present, these guys would have been a good value for money. They've even come up with another product with in-built WiFi for remote monitoring. m.aliexpress.com/item/4000007556126.html?trace I still think of securing the PowMr just to know who between the two is telling the truth (Penn and Teller tell a lie ![]() The PowMr appears to have good reviews on Amazon though.

dejidotun2000: I think it's more than the 102 litres I quoted. Perhaps larger volume (around 209L or 206L or thereabout sha). Currently away from home. I will snap the name plate when home at the weekend. Please bear with me. |

hardywaltz: But i assume the those big lithium batteries have in-built BMSes. At least I am dead sure of the 12v 100amps advertised to me before. I know the 24v and 48v nominal will equally have in-built BMS. I may be wrong in my assumptions so I stand corrected. Connecting another external BMS may disrupt the programmed algorithm of the in-built ones and the long term result of the clash may actually lead to an non-functional effective battery protection, eventually leading to early battery death. And with that in mind, I wager your Installer may have included some unnecessary items, deliberately or otherwise, into the quotation. 1 Like |

Thanks. House, can anyone share their experience with DC freezers. It seems that Felicity offer some and I have come across a brand named bona too. How do they compare amongst themselves and to high efficiency AC models from LG, Hisense etc in terms of power consumption and build quality. ceaser: |

I like the fact that DIYers are opening their eyes to the benefit of AC-coupled systems; I was crucified here on this forum by ignorant people on the possibility of using grid-tied inverters/micro-inverters for off-grid systems. Secondly, the benefit of utilizing high voltage dc inverters for large systems cannot be over emphasized. The overall system dc current is much lower, I2R losses are greatly minimized, and optimal charge rates for the batteries are achieved. Please don't moan about high voltage dc and all the unverified bla bla cliches that make me sick. High voltage AC sources are still much more dangerous to the human body than similar DC voltage sources. See this link for the skeptics: https://www.youtube.com/watch?v=snk3C4m44SY olopan: |

ceaser: I don't think Powr is original neither is it fake. These guys just APPROACH manufacturers who makes controllers to them. They just slap their name on it. So it's just some little difference between the two. So buy whichever one you fancy, probably, the cheaper of the two. 1 Like |

Re: Solar Energy, A Complement To FTA by lexi28(m): 1:46pm On Aug 01, 2019 |
Tilenzua: that's always the basic & best idea. the grundfos sqflex 2.5 does that pretty well. it takes ac/DC voltages up to 300v ac/DC. works with any kind of panels as long as minimum volt of 120v is achieved. idea is to pump water while the sun shines and store in tanks, steel or plastic for use later or immediately. its always cheaper to store water than to add batteries to enable pumping at odd hours of the day. cheers 4 Likes 2 Shares |

Re: Solar Energy, A Complement To FTA by lexi28(m): 8:02pm On Aug 01, 2019 |
Tilenzua: hi, basically you actually need to know the overall head of water your pump is required to pull and pump water to. this means depth of borehole, lateral gradient, and height of overhead tank. popular brands are the Lorentz, and grundfos, and the other Indian and Chinese brands the Lorentz comes with its own controller (with inbuilt MPPT), the grundfos comes with 2 variants, the CU101 (ordinary on/off switch) & the CU200 that has added features for float switch and generator connections. these controllers usually come as one package, but most retailers sell them separately, so be careful. when ordering the generic brands, it is best to ask for the data sheets to determine whether it suits your water supply requirements. some people self the controller from 650k and sell the CU200 for 250k. try Google and jiji, before venturing to go to Alaba. I will search for the contact of Auxwell, I think, the last reps of grundfos I know. some guy in Alaba offered me a pump with 100m head for 130k. it all depends. if you have the funds, go for grundfos or lorentz, (which is more expensive) I will assume the borehole or water source is ready.if a borehole with standard diameter (6" ![]() you will need some kind of rack or pole mount to place your panels, depending on location/size of storage tanks. most steel tanks of large capacity have the solar panels mounted on racks welded atop the tank. if you have space, place panels on pole mounted rack away from trees or tall buildings. you connect wires from panels to controller, and connect wires from pump to controller. the controller is usually placed in a waterproof enclosure under the panel rack, but you could place in anywhere else. your panels are usually wired in series to achieve minimum startup voltage. some Chinese brands I have seen use a 2s2p config of 300w panels, and it pumps water okay. for pumps like grundfos just check Voc of panel you want and calculate how many you need in series to achieve operating voltage of the pump. same goes for Lorentz. cheers 4 Likes 2 Shares |

Trippledots:thanks for the reply. What can i do? i am gradually loosing hope in solar system after inviting 2 engr. from nairaland. The last engr. promised me that it won't happen again after the installation of 580w solar panels(280 poly+300 mono) before i bought two batteries at the same time. The one i connected to the solar system is dead within 3months while the other one that i use with on-grid to charge is still very much ok. 1 Like |
