My answer may be late because am not always on the forum. I hope it still helps. It may be regarded as a TT installation if PHCN only brings live and neutral wires into a building. The following will address solar PV systems in a TT building. The building will need a TT earthing for protection from fault currents arising within its electrical infrastructure. The building and the solar PV both need earthing for protection from lightning strikes. TT installations should have a local earthing with sufficiently low electrical resistance to earth to ensure correct operation of the earth fault protection devices. It is not enough to drive an earth electrode into the ground and attach it to the earth bar in the distribution board. It is very important that the TT earthing is correctly designed and installed and combined with RCDs. Its impedance should be tested at least once a year to be less than 100ohms. Professional support with electrical and solar installation, commissioning, inspection and testing, and trouble-shooting is available at ritility.com. Your ‘electrician’ may be advised to remove the neutral to earth bond at the distribution board if PHCN already does this at the transformer level, and to connect the earth bar to suitable TT earthing of the building. Your solar PV should have its own separate earthing rod. Periodically test TT earthing for sufficient impedance!! An equipotential bond should then be made between the earthing rods, with SPDs, MCBs and AFDDs combined as applicable. A lightning arrester system is also needed. Finally, if a solar PV hybrid energy system with its own battery storage is to be connected in parallel with PHCN grid, it is good practice to install a safety system that will automattically disconnect the energy system from the grid in even of grid outage. This is to prevent back-feed of power into the grid. It seems that, in Nigeria, anyone (ati ájá, ati ẹran) can market themselves as installers of electrical, solar electrical, or other dangerous energy systems without the requisite training, tools, experience, or compliance with safety standards. However, just because it works does not mean that it is safe. NiyiOmoIyunade: 1 Like |

You cant really predict what the present or future occupants will want to power. Once 24/7 power is available, all bets are off. ![]() Your best bet may be a 'pico-grid' of 2-3 inverters in parallel with a single battery bank, and separate meters installed in a locked location. Cheap and reliable and durable is not available! You may have to choose cheap and reliable but not durable, or reliable and durable but not cheap.

Re: Solar Energy, A Complement To FTA by Saipro(m): 2:01pm On Mar 14, 2019 |
mikylon:It would appear your controller might be working fine. My spot diagnosis is, your controller is a PWM type. If you have small cable gauges, long distance between CC and panels, CC heating excessively (leading to derating), inappropriate positive grounding or any combination of the above mentioned, you could have problems like what you're currently experiencing. Next likely culprit is bad panels in the strings. My recommendations - first check controller type - check string currents with a clamp device. If okay, your CC is a PWM regardless of what the sticker states. Minimize distance between PV panels & CC - someone posted a chart showing ampacities and cable gauges. There's another for cable gauges with respect to distance and current. Review both. Easy way out - call an expert. Lots of them here with numbers in their signature |

Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 12:06pm On Mar 15, 2019 |
My Oga Two or more batteries cannot work well together except they be of very similar capacity. Voltage is a very crude approximation of capacity and can be very misleading. Do a full charge for each battery standalone, capacity test each battery standalone, only put back together those batteries that come very close to each other in capacity. Scrap or repurpose the rest of the batteries that cannot hold up under load. earthrealm: |

Hi guys. Please, can anyone tell me if it's necessary to install a thunder arrestor before installing a solar panel. I was told lightning can easily damage the panels if it's not installed. Also, can anyone give me an estimate of how much it will cost to install panels and a solar charge controller (I know the price will vary based on location, I want to have a baseline to work with). Thanks. |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 12:14pm On Mar 15, 2019 |
Neither myself nor my source have these in stock currently Sir. But say I were to offer a 340w Tier 1 panel to you at 70k thus severely undercutting the prevailing market price, you are still paying 16k extra for additional 40w when I could sell you a similar Tier 1 300w for 52k. Except you have a specific use case for a 340w panel, the price premium may not really be worth it. These current set of 300w Mono Perc are marketed as substantially more efficient than the older technology by Canadian Solar. DUNKA: 1 Like |

NiyiOmoIyunade: WOW, THATS a mega station 10kw is super massive, are you offgrid?, or intend to go offgrid. yeah, the inclination is high, however i think the direction the panels are facing doesnt impact as much as inclination. did you consider using tiilt legs solar racks to balance out the inclination?, or you feel the additional complexity of the tilt leg racks isnt worth the extra harvest? for my battery bank, i have charged and load tested all the batts, with a standard 100amp load tester like i explained previously, and they checked out ok...hence my dilenma |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 4:10pm On Mar 15, 2019 |
The extra 3.6Kw I want to acquire are against future upgrades, I don't see the price of a Tier 1 panel shifting by much in the next two years. My base load is about 1Kw at least - I currently run 2 ACs virtually 24/7 on weekends and plan to add one more AC and run all three from AM to late evening at least. All the 10kw of panels will come in useful on such heavy load days especially if there is plenty of cloud. Yes I am 90% offgrid. I do not want to go through the trouble of adjustable legs e.t.c in a leased house For your battery bank, I recall we differed over how to perform a load test - for a fully charged 12v 200Ah battery a, 100amp load applied for less than a minute has a poor chance of showing up a bad battery except the battery has suffered significant degradation! You will need to apply the load for a longer time say at least 30 minutes. earthrealm: |

Re: Solar Energy, A Complement To FTA by Saipro(m): 11:15pm On Mar 15, 2019 |
mikylon: An MPPT might behave as a PWM if the voltage headroom is too small (not so in your case). The voltages you're dealing with are sufficiently high to give dangerous shocks in the daytime. Troubleshooting won't work so well at night either. I think an expert on-site review is your best bet. Pick one you're comfortable with. |
