On must power I use option 3 for charging which is sealed flooded acid(I use sealed flooded acid battery n lithium iron phosphate(glorious battery)) They quoted 25w in their manual but its pure lie. The best way is to use energy saver mode so when there is very little load it goes on standby however even if you running a load of 39w, know that what ur battery is seeing is 130w. Their charging system is awesome(mine is adjustable charging current), I have no issues though I use a 24v system. earthrealm: |

I have a small inverter with self consumption of about 5w. I use this at night n for light load operations. I use my must for appreciable loads. I switch over from one inverter to the other without my electronics going off Ferdiwar: |

DMerciful: yeah, i was using option 6 - open lead acid 14.8v, ytday i switched to option 7 calcuim-15.1v, lemme observe and see, though am seeing some improvements already yes i use the energy saving function, once your loa is less than 35w, it will trip off, a bit iffy for me on cold nights when i have only 2 energy saving lights on,16w each, it usually goes off...unless its 18w each. have you checked the idle consumption when on energy saving mode? |
Re: Solar Energy, A Complement To FTA by JUO(m): 4:05pm On Apr 23, 2017 |
earthrealm:is same bro except the inverter didn't detect any load and switch off |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 9:57pm On Apr 23, 2017 |
Idle consumption is less than 5w cos it just comes in intermittently to check if load has be added else it goes off again earthrealm: |

@abunafiu, nope i didnt just water them...have tried charging them at 61v/ie equalization setting for upto 24hrs, at 3hr internals with usage inbetween...still no show. ait o...u said ur bank drops to 49.2v by 6am powering the loads u listed?. how many batts do you have?/whats ur bank size in AH? MINE DROPS TO 49.2V under 8hrs just powering 2 ceiling fans 75w each. 3 x 16w energy bulbs, 1 samsung 46inch led tv..90w or so, dvd hometheater 85w (a few hrs inbetween) i think the drop to 49.2v is too rapid, i used the mecury set b4 transfering them to the villge, they stayed at 50v for almost the whole day! abi is this normal, and am just anxious for nothing? |
Re: Solar Energy, A Complement To FTA by JUO(m): 10:16pm On Apr 24, 2017 |
earthrealm:this your battery is not performing poorly with the way you are painting it for a standalone system. You have calculated over 400w from the list above for a battery that has worked without any assistance for over a year and without adequate charge for a very long time. I think the battery is dropping in performance cos of steady use. Try and introduce solar and see what happens. Is never advisable to use only inverter and battery and expect your battery to do over 700 cycles in some cases you can do 700 cycles in less than a year 2 Likes |

My journey for RE has started, I have the following 1. 1400va Kevin inverter 24v 2. Epever 30a, 100v CC 3. 4×200w solar panels, acquired from our uncle in the house, GeorgeD1( yet to be received though) 4.watt meter I rewired the house & have a dedicated DB for the inverter Outstanding 1.Pv connection cable 2.breakers 3.BATTERIES 4.combiner box 5.Pv mounting kit or frame should I choose ground mount 6.earthing protection for Pv & inverter DB CC Dmerciful GeorgeD1 Efuro Bigrovar Juo Abunafiu More questions coming please 1. The max for my CC is 780w, can I use the 4 panels totalling 800w? If yes what's my best way of connecting them? 2. If my CC Max rating is 30a, won't it be a problem if my CC is producing almost this on a constant basis because of my 800w setup 3.can I use normal 10mm cable or it's best I go for the amoured cable Distance from panel to CC will be 7m Distance from CC to battery will be 12m These distances is a result of optimum position for the inverter & battery The location of the CC in my balcony is safe from water but battery at ground level won't be Should i work out a way to put the battery there, I can't put my inverter there Meaning if my CC & battery is at Same location, my inverter will be inside the house 12m away from Battery Option 2 Run cable straight from Pv to CC-battery-inverter all located inside the house, 19m My only concern with this option is ventilation So how do I go about this please |
Re: Solar Energy, A Complement To FTA by mank1234(m): 8:38am On Apr 25, 2017 |
Put inverter, cc and battery at same location. If DC wire is too long especially at lower voltage, more loss will occur. It's easier to channel AC wire to/from the inverter DB. Go for 2x2 parallel/series connection for the panels. 10mm is okay for all connections except for battery to inverter. As per ventilation, use extraction fan with piping to expel air outdoor. therealMcCain: 2 Likes |

Re: Solar Energy, A Complement To FTA by earthrealm(m): 9:50am On Apr 25, 2017 |
JUO: got the battery early oct 2016, so still fairly new, not upto 1 yr, my next plan is to hook up my WATT METER to the inverters output and hv the total consumption in watts, so i can have a clearer picture and compare notes with folks running a similar setup on this thread. why am a bit concerned is that when i had 2 x 200ah sealed batt with 1.4kva luminous, when new, it lasted 3 to 5 days of almost same load, though 6pm to 11pm daily usage, the mustpower 4 x 200ah flooded batt setup barely lasts 2 full days noon to 12am usage and voltage will approach 48v, and lower |
Re: Solar Energy, A Complement To FTA by shiftmarket(m): 10:07am On Apr 25, 2017 |

Re: Solar Energy, A Complement To FTA by efuro(m): 11:01am On Apr 25, 2017 |
therealMcCain: welcome to the world of DIY congrats on your acquisition. My dear brother, you raised good questions from valid observations these are: distance, away from water, ventilation, perhaps the capacity of CC. But your statement below: “The location of the CC in my balcony is safe from water but battery at ground level won't be” I can't put my inverter there ! Shows you don’t have a problem (at least to me). However, I wonder why you can’t put inverter there?. If it is for security reason, I can reason with you. Solar devices are very expensive & attractive to undesirable elements, it’s when they are safe that you can enjoy 24hrs power. We all know in ideal situation CC/other devices are best located near PVs (where possible) to minimize resistance or loss of harvest and frequent replacement of devices. The balcony would have been the best place to install you gadgets. I think monzpower in the house have plenty of such pix to convince you. But your insistence of not placing the inverter there leaves you with locating it 19m away. Locating it insider Sincerely I don’t see 19m too far away. First it will guarantee that your CC is safe remember: “The max for my CC is 780w, can I use the 4 panels totaling 800w?” Yes In STC, you can get 800w but it is rare (even when mounting inclination is seasonally perfect). Your CC is safe because of resistance as a result of cabling (even if you step up your cable from 10mm to 35mm) not all harvest is delivered. As for ventilation, CC are designed to work optimally at room temperature but I hope ur CC has inbuilt fan? if It has then you have nothing to worry. If not as a DIY, pls improvise just to be double sure. Then you have the opportunity to maximize the cabling distance between CC-Bank-Converter. Finally, to question 1 = use the solar panel configuration of 2 by 2 to optimize AMP & VOLTAGE. @ open voltage of 48.2v as shown by Oga GeorgeD indicate it will have enough Vmp sufficient to push through ur 19m cabling. Please do not be tempted to connect all the panels in series (i.e. 1 by 4). to question 2 = using 2 x 2 config will give you a steady amp below your 30amp cc mathematically around 16.8amp. to question 3 = your 10mm is more than sufficient for 800w. if I omit any other item. am sure the house will add to it. my regards! 2 Likes |

efuro: Thanks I will send a snapshot of the balcony later I intend installing the CC up but if the battery is placed at ground level, it will be exposed to rain cos water gets there when it rains Secondly, everyone entering my flat will see my setup at once which I don't quite like, then there is the issue of operating the inverter by coming out of the house |
Re: Solar Energy, A Complement To FTA by Ferdiwar: 9:31pm On Apr 25, 2017 |
therealMcCain: I will advise you to install all the system inside as it will enable you to monitor and control them at will. Just like efuro said try to determine if the CC has inbuilt cooling system and as for the batteries and inverter they can operate optimally at room temperature and in the case of abnormal raise in temperature due to lack of ventilation and pother factors then try the extractor fan as suggested. |
Re: Solar Energy, A Complement To FTA by bigrovar(m): 10:53pm On Apr 25, 2017 |
earthrealm: Your batteries seem fine if the main concern is load voltage. Lead acid batteries experience voltage sag once load is applied and flooded are worse for it. What matters is the rest voltage. Rest voltage is the true reflection of state of charge in the case the battery rest for 3 hours with no charge no load. My setup is a 2 12v 220AH mercury tubular battery connected in series. My inverter pretty much runs 24/7 due to horrendous gird power situ in my area. Just got off a 20 days zero power situ. Anyway with an average night load of 150w 17:00 (when solar panels charge diminishes) to 07:00. Or 1300wh later battery voltage is at 24.9 with load. Once load is removed battery voltage jumps to 25.1.. I would be concerned the day my battery rest voltage stays at 24.4 (never happened in over a year of use) why am a bit concerned is that when i had 2 x 200ah sealed batt with 1.4kva luminous, when new, it lasted 3 to 5 days of almost same load, though 6pm to 11pm daily usage, the mustpower 4 x 200ah flooded batt setup barely lasts 2 full days noon to 12am usage and voltage will approach 48v, and lower U need to come up with objective figures like watt watt hours. If I discharge my battery at C100 they will last longer than if discharged at C20. The previous figure you posted regarding consumption showed u discharge your batteries at close to C20. U might want to reduce that figure to put battery peukert effect in your favour. 150w on ceiling fan is too much when same figure will run 5 rechargeable fan at high settings. 25w in this day and age does not qualify as energy safers and if u hit some cash. Consider deprecating that TV. My LG 43 inch uses just 20w. Your ceiling fan consumes more electricity than my deep chest freezer. Also note that u have established that those batteries are having serious charging deficit. Flooded batteries love their absorption performance would fall off the cliff if denied for long. The attached image shows my night load. 2 fan, 2 balcony lighting points. It stays like so till day break.

Re: Solar Energy, A Complement To FTA by pranil(m): 11:38pm On Apr 25, 2017 |
emmaniche: My suggestion is to use one of the hybrid inverters like ipower which can be monitered with software developed by user groups. e.g. see my setup . The other inverters like SMA /schinder/Voltron are all expensive to start with . That way you can control also http://emoncms.org/ghatikar With a software like ICC you can even change the time the inverter uses solar and not NEPA e.g. during weekdays use solar not Nepa weekend USE nepa even if solar is available ( to avoid prematurely discharging batteries) CCTV will not give you control and too expensive to continuously monitor because of high data rate used of video feed over internet |
