haslaw:I use one such inverter, it has been working fine but with minor issues; There is a power saving feature which is supposed to turn the inverter off if the connected load is low or zero.whenever I enable that feature the inverter output begins to rapidly switch on and off; I have not been able to realize more than 280W from an installed capacity of 600W solae panels, there is a voltage drop of 2v between the solar panels and the inverter though so I really can't assume the fault is from the 500W inbuilt mppt charger yet. 2 Likes |

haslaw: Charge controllers generate a large amount of heat. So does the AC charger inside the inverter. I want to minimize the heat sources inside my inverter, hence I prefer an external controller. Also I am not limited to the voltage and amount of watts I can hang by the controller within the inverter. 1 Like 1 Share |

dejidotun2000: A voltage drop of up to 2v is high and will definitely lead to loses. Could it be that the cables from the solar panels to inverter are undesired |
Re: Solar Energy, A Complement To FTA by dejidotun2000(m): 5:27pm On Dec 14, 2016 |
haslaw:I am pretty certain that the cable is undersized for that application, its 8AWG. I intend to run one more length of 8AWG cable in parallel with the existing one. |

chris81964: Most of them are transformer less. There by eliminating heat, the sunny island inverters are the best but unfortunately also very expensive. 1 Like |

haslaw: haslaw, i think the question really should be, what is the conversion efficiency of these built in charge controllers? i personally like to think that you cannot be a jack of all trades so i tend to avoid products which try to deliver so many functions all in one. experience has taught me that there's always a trade off. unless we can find a way of comparing the performances of the separate functions and can confirm that they are indeed at par with their stand alone counterparts, i think savvy peeps will still prefer to go for products that will deliver reliable performance while giving the high efficiency most sought after. 4 Likes |

Good morning house, I hail all gurus in the house, I urgently need to get Midnite solar surge protector. My solar system was commissioned yesterday without surge protector. Please where in Lagos especially around Ikeja can I get midnite surge protector 115v and 300v. Thanks. |

chris81964: There is a cooling system in the hybrid inverter such as fans and cooling fins that fairly takes care of the heat generated same as the non-hybrid. Most of these hybrid inbuilt MPPT charge controller have high MPPT like 60A, 70A or even 80A. That should be enough for future expansions. 1 Like |

Just like complexities in living things where a kidney failure can cause the failure of the entire body so it is for a system that combines almost all functions. a failure in one section on the unit can render everything useless ![]() ![]() ![]() ![]() Longevity of inverter depends on usage conditions like loading, surges, stabilizer protection etc. A solid inverter can fail prematurely if abuse.....fyi non of my inverters have failed...all functions intact. tivta: |
Re: Solar Energy, A Complement To FTA by haslaw(m): 9:10am On Dec 15, 2016 |
GeorgeD1: Thanks George, but when you look at it, there is no device that doesn't have some sort of trade off. Even the stand alone inverters still has its own peculiar drawbacks. Peeps not using hybrid have not been able to give any real reason for not liking hybrid. I think the biggest issue is peeps not wanting to try new things and would rather stick to what they are already used to. We still have people who stick to their noisy generators than buy use inverters. 3 Likes |

haslaw: We have installed inverters with and without controllers. My personal inverter has two large fans to keep the components cool. The HF hybrid with a much smaller form factor also has two fans to perform the same function in addition to cooling a charge controller. If you have any experience with charge controllers they generate an intense amount of heat. The Schneider MPPT 150 60 has a huge heat sink that radiates a great deal of heat (you can't keep your hands on it for extended periods). The FM60 has a single fan while the FM80 has two. If you want to believe that a single unit will be as effective at removing heat as two separate units, go for it. We had a fan failure in one the hybrids and the chassis of the inverter go so hot that we were afraid it would catch on fire. I can't imagine pushing 60 to 80 amps through one of these devices. I have attached pictures of controllers and the inverter. The form factor of these HF inverters limit what you can do within it. 2 Likes 1 Share

please house, someone is convincing me to go for a locally constructed inverter. how safe is it? and does it affect health and duration of the batteries? I'm not using solar, just charging with mains and generator. what are the pros and cons of such inverter? a 3000w inverter. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 1:36pm On Dec 15, 2016 |
CoolKizzy: f**king run!. not a good idea, usually doesnt end well, for the owner/battteries/inverter fire, overcharging, under charging, runaway charging, losses, heat, smoke etc, are terms you will get accustomed to when using locally fabricated inverters |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 6:12pm On Dec 15, 2016 |
Dont go for locally made inverter as their charging system is most atimes poor and will ruin your batteries within a short time. Go for foreign known brands and they are all-in-all cheaper. This is not the time to be patriotic or politically correct! CoolKizzy: |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 8:27pm On Dec 15, 2016 |
haslaw: haslaw, we could go back and forth on this topic but I think the bottom line still bothers on efficiency. how do these hybrid inverters compare to their stand alone counterparts in terms of conversion efficiency? until we begin to see hard empirical data, all we will be doing is argue based on emotions. |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 8:40pm On Dec 15, 2016 |
coolkizzy, a local made inverter nearly burnt my house several years ago. after that lucky escape I decided to stay in darkness for almost three months while I gathered money to buy a replacement inverter. I later returned the inverter to the guy who assembled it. I never went back to collect it to this day. 1 Like |

Pls which is better, ritar 12v 200AH, or new ZTE or agisson 2v 500Ah battery. Or any reliable brand on d market. |
Re: Solar Energy, A Complement To FTA by haslaw(m): 5:57am On Dec 16, 2016 |
GeorgeD1: Yeah... You are correct. I'm not for or against any type of inverter really. I just want to get advice on the type of inverter to buy as I'll be buying an inverter and charge controller next month |
Re: Solar Energy, A Complement To FTA by chris81964(m): 11:28am On Dec 16, 2016 |
haslaw: You can buy a Schneider SW and the charge controller that goes with it. I also have my Rich Electric Invertek Combi for sale too.

CoolKizzy:if u wanna buy it, go for 12v system dat charges or 24 system dat doesn't charge.. although d best thing to do is charge wit solar... depending on the maker, local inverters are not that bad dis days, it has improved a lot ...buh be sure u trust d seller ... imported inverters could catch fire too... Google microtek inverters... mosfets is usually d major source of fire... make sure the place u install d inverter is well aerated and lastly be sure it has auto cutoff function when using excess load, if not, Neva over load any inverter... 1 Like |

dejidotun2000: The power save function has kind of like a ping function. It has a minimum threshold it needs to see to function. So your energy bulbs react to that ping and come on and off. You can disable it. |

Good morning house. I got an installer in my area, we agreed on installing a 130W pvc, 100AH solar battery, 5 DC bulbs. But the amusing stuff was that he said we don't need charge controllers. He also advised I use my Famcare inverter instead of sticking my plan of going DC. I need an advice house cos I don't wanna go for what I may regret. NB: I have a plan of upgrading ma panels and maybe batteries next year. |

In as much as i like providing quick info on this forum, take your time to read previous pages and be wiser for it. after reading you will find yourself calibrating the said 'installer' that said you dont need a charge controller. When i joined i went through all previous pages and i am wiser for it...thanks to all the gurus in the house. Papishi: 4 Likes |

Very true... Invest the time to read up, so you can recalibrate the installer. ![]() I have one like that, always ready to argue and not willing to learn. |
