badaru1: My apologies if I pass myself across as a Guru. I bought two of them with the intention of using them as bulk chargers and I had never tried using them otherwise; I have never attempted to verify the full capabilities neither do I have the technical know-how to do so. They were bought used and never came with spec sheet. I am happy with the performance for what I bought them for and like I said before, I will rather have this charger than nothing. |

durodee: Was your system grounded when the lightning strike happened ? |
Re: Solar Energy, A Complement To FTA by durodee(m): 6:18pm On Jul 17, 2016 |
bigrovar:It was. That was the 2nd time in about one year. Initially depended on the house grouding but after the first episode, I decided to reground the whole house AND the solar system separately (making 2 for house and 3rd for the solar setup). I also bought the Midnight solar thunder arrestors (ac/dc) but unfortunately delayed connecting it until this last episode. I have since connected the DC arrestor BUT made sure no grid (AC) connection to my inverter at all. So there is now two parallel system in the house and not automatic changeover. I have external charger connected to Gen only.

durodee:abandoned keee durodee:abandoned keee are always a busy person and I don't want to disturb at work, d hybrid setup is getting famous these days n it also save the stress of getting another cc, besides i like them because they give full details of all yr setup...... Is your hybrid inverter integrated with pwm or mppt controller? |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 7:31pm On Jul 17, 2016 |
durodee: From all I have read about grounding .. all system in an off grid setup should be connected to the same ground in a process called bonding. Your panels and their frames and your controllers batteries inverters and all appliances in the house should all terminate to the same ground. Grounding separately (again from my readings ) defeats the purpose of creating 1 path of least resistance to ground. Might want to look it up. I have my system setup this way although the controller and batteries are yet to be connected to ground. |

Battery Condition This section describes some of the variables used to describe the present condition of a battery. • State of Charge (SOC)(%) – An expression of the present battery capacity as a percentage of maximum capacity. SOC is generally calculated using current integration to determine the change in battery capacity over time. • Depth of Discharge (DOD) (%) – The percentage of battery capacity that has been discharged expressed as a percentage of maximum capacity. A discharge to at least 80 % DOD is referred to as a deep discharge. • Terminal Voltage (V) – The voltage between the battery terminals with load applied. Terminal voltage varies with SOC and discharge/charge current. • Open-circuit voltage (V) – The voltage between the battery terminals with no load applied. The open-circuit voltage depends on the battery state of charge, increasing with state of charge. • Internal Resistance – The resistance within the battery, generally different for charging and discharging, also dependent on the battery state of charge. As internal resistance increases, the battery efficiency decreases and thermal stability is reduced as more of the charging energy is converted into heat |

Re: Solar Energy, A Complement To FTA by bigrovar(m): 2:54pm On Jul 18, 2016 |
Monlo: Well there is not much to add about grounding. The idea is to create a path of least resistance for rouge electricity to pass through to ground. Electricity is always looking for ground and always trying to find the easiest part to the ground (ground as in earth) the easiest part is the most conductive. e.g, when you touch a naked electrical wire without proper insulation, lets say you legs happens to be on water and you are not wearing a shoe, once your touch the wire, the electricity would see you has the easiest path to ground (considering the human body is highly conductive being made up of water and all) and pass through your body to ground. Grounding your system creates a path for this wrong electricity which could come from lightening or electrical leakage or short circuiting of any of your device.. The ground creates an lazy path for them to ground so they avoid passing through your expensive devices and damaging them on their search for ground, The first step for grounding is getting a grounding rod. Usually a copper coated rod about 6 feet long. You dig a hole about 2 feet deep, always advisable to add industrial salt and charcoal to help with the conductivity of your grounding rod (especially when it rains). The rod is hammered into the hole where the salt and charcoal has been added. next it is assumed that the house wiring already bound all the earth wiring from all your socket (The top part of the 3 pin plug used generally in NIgeria) all that earth wiring is bound together in your distribution box and are merged into a single copper wire which should then be connected to the rod you just hammered to the ground (outside your house) Most houses have earth wires and ground rode (although most ground systems in many houses are not active due to the type of ground rode used) anyway.. once this is done.. all appliances in the house that connects to electrical socket is automatically grounded. next step is how do you ground your solar setup. In my case (and am no guru on this subject) My panels are ground mounted not roof mounted. what I did was to connect a 16mm copper wire to one of the legs of the ground mount and have that connected to the ground rod. These ensures my panel mount frame is grounded. (note it is advisable that all metal or conductive materials used in your setup including battery box (if made of metal) should be bonded together and have a wire attached to the ground rod. grounding your panels,You just take a wire from the negative of your panel and connect to the ground rod, another cable from the negative of your battery should also connect to the ground rod. Edit: Turns out the battery and controller do not require grounding. The grounding of the inverter should suffice. However many documentations including that of many charge controller recommend ground the negative terminal of the battery to ground.[b][/b] some inverters have ground setup with proper labelling, that also should be added to the ground rod. in other to avoid a situation where you have wires running to the ground rod, all those connections should be bonded together using something like a combiner box and one cable should then connect to the ground rod. That is all I know about grounding. Caveat. I am not an electrician and most of what am saying are based on what I learned from talking to electricians and also from readings. this is by no means meant to be a guide nor should it be taking as one. Best to be used as an aid for further reading and also have basic knowledge of what grounding is about and why it is important. It would be nice if other gurus in the house can shade light on this issue. 2 Likes

Below is the ground for my panel. Don't know if it is adequate will appreciate input. Also note that some charge controller like epsolar A tracer series have positive grounding hence it is the positive of your battery and your panel in face the positive of your DC component that needs be ground in such a case. Edit: The epsolar diagram indicate the need for grounding of the controller via the battery.. however has stated below this message. controller and battery grounding is not essential especially if the panels and inverter are well grounded.

Please do not connect the negative of your panel to ground ooo. Panels have a hole on the frame for grounding!. Also do not connect the negative of your battery to ground ooo. Grounding your inverter covers that. Positive, negative and earthing terminals all have their separate work. Let's not get it twisted My 2cents 2 Likes |

life707:exactly, the Solar frame is the ground for all solar panel in d universe. Anyone can confirm this by checking the frame on the back side of their panel,u will definitely see the ground logo there. |
Re: Solar Energy, A Complement To FTA by mank1234(m): 11:06pm On Jul 18, 2016 |
life707: They're two methods of connecting solar setup viz grounded and ungrounded system. Gounded is futher classified into positive and negative grounded systems as stated ealier. Grounded here is not same as bonding metal parts. Both methods have advantages and disadvantages. In grounded system, (let assume the -ve terminal is grounded, touching the positive terminal of a high voltage string can result in tremendous shock since there's a return path through earth. However, such a system is less prone to damage by lightening since there's a ready path to earth to divert the charges. Grounded system is not suitable for transformer less inverter due to the nature of their internal circuitry. Lightening current traveling through 1m length of wire induces a voltage of 1kV. For ungrounded systems therefore, surge arrester should be ideally installed close to the charge controller to protect it and additionally close to the panel (across the +be and -ve) to ensure that the lightening does not induce voltage above the limits the panels can withstand (most panels can withstand maximum of 1kV). N/B 1) in grounded system, one terminal is connected to ground at just ONE point, while in ungrounded system no connection to ground is done - the voltage is floating with respect to ground. 2) the fact that your setup has not been hit by lightening since doesn't mean it cannot be hit tomorrow. Precaution is cheaper than replacement |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 2:31am On Jul 19, 2016 |
life707: Thanks for posting this. My electrician also said the same. So what you are saying is that the grounding of the panel mount covers the panel and the inverter covers the battery and by extension the charge controller. Hmmmm just the basic diagram of my controller stated that the controller is to be grounded via the battery ( from the negative terminal). I guess more reading need be done on this regard. |
