Can i get a hybrid 7.5kva to run 4x220ah batteries instead then with 9x350watts panels and please who can give good and durable hybrid inverter brands to work well with my luminous batteries? smallsmall: |
Re: Solar Energy, A Complement To FTA by Valto(m): 10:00pm On Feb 18, 2022 |
Bolatitodavies:your 4pcs 220ah tubular batteries might not be enough to efficiently run a 7.5kw inverter, u need atleast 8pcs. 4 or 5kw hybrid inverter is your best bet for now. |
Re: Solar Energy, A Complement To FTA by alstacs(m): 2:46am On Feb 19, 2022 |
Valto: Kindly shed more light on this. Even if the 4 batteries, at present, are sufficient to power his load load for over 24 hours? And the size of the inverter is to accommodate future expansion of the battery bank? 5 Likes |

alstacs:just 4 pcs of 220ah tubular might not be enough to power lets say a continuous 3000w to 4000w load when the sun is down. it defeats the purpose, if he only have 3150w panels and just 4pcs lead acid batteries to use on the proposed 7.5kw inverter. in essence he need to upgrade his battery bank and solar panels capacity first. 1 Like |

Re: Solar Energy, A Complement To FTA by Bolatitodavies: 9:27am On Feb 19, 2022 |
Yes my load less than 1000w, why i asked was cuz i feel my technician wants to charge high for 5kva when the money is sufficient to buy 7.5kva. Is there any 5kva hybrid that costs 500k+? gadgetplanetng: |
Re: Solar Energy, A Complement To FTA by Valto(m): 10:18am On Feb 19, 2022 |
gadgetplanetng:if his load is truly 1000w, why suggest 7.5kw inverter for him, isnt that an overkill? he simply need a 5kva 48v inverter. Bolatitodavies:your technician must not buy everything for you, u can buy things by yourself. u can get ANERN 48V 100A mppt, sorotec 48V 80A mppt, EPEVER 48V 80A mppt all at less than 400K. 1 Like |
Re: Solar Energy, A Complement To FTA by gadgetplanetng: 11:08am On Feb 19, 2022 |
Valto: Probably to allow for future expansion. I've a 5kv hybrid and I'm not sure my load has gone above 250w before but at least I know in future I only need to buy panels and batteries as necessary 2 Likes |
Re: Solar Energy, A Complement To FTA by Bolatitodavies: 1:01pm On Feb 19, 2022 |
I have luminous 4kva inverter already with 80amp felicity mppt charge controller with 4x220ah and 9x350watts solar panels, so my new technician is advising i switch to hybrid 5kva adding 180k extra to my 4kva inverter nd mppt charger which i feel im being robbed. Insead, i feel with 180k extra, i can get hybrid 7.5kva instead or is he offering me a good deal? Valto: |
Re: Solar Energy, A Complement To FTA by Valto(m): 1:44pm On Feb 19, 2022 |
Bolatitodavies:it is not a good deal, unless he is giving you a growatts ES model. but which brand of 5kva is he planning to give u? |

Bolatitodavies: I don't think you are going about this optimally. I scanned through your message and I still did not find why you are upgrading. Why do you need a 7.5kva inverter? You said something about planning for future expansion. If that is your only reason then it's the wrong way to plan. Solar is not about throwing money about but rather making every money you spend count. Efficiency is key in any system. Rather than just buying the highest rated solar components you are better off first identify your load. The character of your load in term of timing and load type. Typically the type of inductive load like water pump, freezer and non inverter AC and Fridge are things that determine size of your inverter. Plus the number of appliances you run concurrently. Once you have this figures then you size your inverter appropriately. One thing you should note though. The load you are placing on your offgrid setup must be one you can generate back to the system either via solar or via generator / NEPA. If you take more than you can give back to the system, your setup would not last as you would over use your battery and kill it before you get economic value from it. The first thing to consider is your generating capacity. Solar or NEPA (case in point I once lived in a place where 20 hours light a day was guaranteed that factored into my setup) When you have your generating capacity, you then optimize your load to use below that capacity such that your battery can get daily full charge. Next is your battery it should be able to take your night load and be at about 50% dod by morning (Presuming you can take it back to 100% soc by noon) Then your inverter should be sized to be able to operate at about 30% capacity when you turn your load. Over sizing inverter besides being a waste would also put a heavy idle load on your battery. Solar has a good second hand market, if your needs radically increases you can also sell and upgrade. (Happens here all the time) Best way to plan for the future is ensure your installation panel like where you installed your inverter or cc has enough space to do a drop in replacement for a bigger inverter without much rewiring. 13 Likes 3 Shares |

Well said. You have done justice to this. Just to add that just like every invention time brings better solutions. A while back 250W panels seemed the peak now there are 600+ Watt panels. In fairness to your engineer what he had installed for you was probably the best he could do for you balancing cost and efficiency at that time. Best practice is to have installation based on load sizing. Don't just throw capacity around carefully do a power audit and focus on your actual needs bigrovar: |
Re: Solar Energy, A Complement To FTA by samnaija: 1:20pm On Feb 20, 2022 |
Thumbs up ,to u guys. He should probably focus more on generating energy. Invest in more panels and expand. No point jumping into 7.5kva . Expand your solar arrays, this way you will eventually be more self reliant , without grid or generator.. |

Re: Solar Energy, A Complement To FTA by Michaelondon53: 3:29pm On Feb 20, 2022 |
Good morning everyone. I don’t know what to say actually because i am speechless, angry and unhappy Got these so called two (2) brand new AGM batteries in December (100ah each) 1kva psw inverter and two (2) Of fairly used 180wats solar panels connected in parallel. The batteries have NOT been giving me the value for my money... with just 1 led tv of 75wats in which i still often activated the power saving energy on the tv and also reduced the contrast and brightness of the tv to 5% which made the tv backlight so deem just in the effort to save energy. Also I have 5 led bulbs of 5 wats each with just 2 constantly on and the other 3 on at intervals and off almost immediately after usage. I also have a 12v dc standing fan which I normally turn on at lowest power speed just to save more power. Amidst all these my strategies of minimizing power usage. What I just get from my 200ah battery in total is 5hrs on a full charge. I.e my loads include 12v dc fan at lowest speed, two 5wats bulb constantly on and the other 3 5watts bulb on at interval ( total interval bulb-on time do not exceed 45mins within the 5 hrs being supplied by the batteries. And 75 watts led tv( with energy server on and both brightness, contrast and backlight reduced plus inverter standby energy consumption which is 3% total % shown on the inverter when all this loads above are on range between 10% -12%( this is plus inverter standby every consumption inclusive). The two batteries connected in parallel will then run for 5 hrs between hours of (8pm -1am) (which are the time I do switch on the inverter.) running from 13.1 - 12.1v or 12.0v in which I immediately switch it off so as to maintain 50% depth of discharge. Is this normal? Due to my curiosity, last night I disconnected one of the 100ah batteries and connected the other one just to know how long each 100ah would give. Low and behold. With that same exact load it gave me 2 hours (I.e. 10pm -1am ) battery running from ( 13.0v - 10. 9v) before the inverter came out screaming like a mad dog. The loads on the inverter read 10% (with inverter standby energy consumption inclusive) Calculating it this should be less than 90watts of a 1kva inverter becos 1kv inverter are not properly sized they are often between 800VA and 850VA so 10 % of 850 is around 85wats to 90wats as load consumption. How come will 100ah now give me just 2hours on a full charge starting from 13.0 or 12.9 Please gurus in the house kindly help me join mouth for this matter. I swear I don tire ! You remarks-advise and troubleshooting skills would be highly appreciated. Thanks |

Penuelseun:yes batteries reads 14.3 , 14.4 daily sir (I.e whenever I use the solar panels and 13.9V when I use nepa. Sometimes I use the two simultaneously, to quickly get full charge whenever there is nepa Charging parameters : solar panels alone when there is no light. And both simultaneously (solar and nepa ) when there is nepa light |

Re: Solar Energy, A Complement To FTA by blockgeek69(m): 8:07pm On Feb 20, 2022 |
I recently installed a solar inverter system with the following setup: 1. 4 solar panels (each 300watt) = total 1200watt 2. 24v inverter system 3. 2 units of 230amp battery 4. 60amp PWM charge controller My load at max capacity is 500 watt and could go as low as 300watt during midnight hours. But I noticed that my battery charge depletes faster than its charging, is it supposed to be so? What i mean is, my battery could be 26v after fully charged with no load, but after 4 hours of use, it falls down to 24.5v even when the solar panel is still charging the system. So I am beginning to wonder if this is normal or there is a problem with my system configuration or the charge controller itself since i am using a PWM cc. Please gurus in the house, i need your input. |
