chris81964: Can I ask why is there Inverter generator changeover in the last picture ? The Conext SW has a separate DC panel and optional charge controller with GEN input in . In fact the correct way to do a clean job will be to use Conext SW charge controller , DC breaker and connect generator start to inverter . Right now the customer is spending more than half a million on inverter and getting a 200 K inverter function 1 Like

Dreamflyin: From experience and from what I can see and taking into consideration all that has been said so far, those two devices called charge controllers are your biggest problem. They are not doing their work and the sooner you change them and have a 'real' professional reinstall your system, the sooner you will have a functional system and be happy. A friend of mine contracted a 'professional installer' who supplied everything needed including a charge controller that was not in the list of the options he gave. At first my friend was excited and was almost insisting that I use the same guy to do my own. I did not agree and went ahead after serious research gathered all the components I needed and got an installer I could direct to do the installation. It was only when my setup came online that my friend realised that his system was not performing optimally and already one of his batteries was going dead. I eventually convinced him to replace his charge controller with the brand I was using and when he did, the difference was as night is from day. Meanwhile he just realised that what I had always told him was true, that his charge controller had never, since the system was setup, charged his batteries full, so the batteries were gradually dying out. The moral of the story is this, you need not be a professional. But you should not be afraid to research the subject in question and arm yourself with as much information as you can such that if you were to DIY the system, you will make very few errors. Also research the pitfalls others had experienced and how they solved them. At the end of the installation, you will be better off for it. Always bear in mind that EVERY SOLAR SETUP IS AS GOOD AS THE CHARGE CONTROLLER. Spend a million bucks on an inverter, another two million on batteries and a million on panels and top grade of all other components... and install a scrap charge controller, your setup would be scrap. In other words, the charge controller is one single most important component that should be top grade even if you cannot afford top grade in the other components. Cheers. 4 Likes |

pranil:Very intelligent question. The reason is to allow us to bypass the inverter if we have a problem or need to service it. The SW has an optional AC breaker panel. It cost over 100k. The changeover is less than 10k. We used individual breakers in addition to the change over to arrive at the same result. Schneider does not make it mandatory that you use their controller. I used an 80 amp FM that cost half of what the 80 amp Schneider controller costs. The generator start works if your customer has a generator that can be started by remote contact. FYI. Here is the wholesale prices of the items you mention 2524 N393k AC Panel / breaker N94k DC Panel / Breaker N88k 80 amp C/C N392k Gen start N50k. Retail price is higher. I saved my customer N450k by being creative and accomplishing the same thing. But I am sure you have a better idea. Please share so that I can try it. Thank you for the lecture though. 1 Like |

Re: Solar Energy, A Complement To FTA by Saipro(m): 11:22am On Jul 31, 2016 |
chris81964: Kindly explain the above quote. My presumption is, charge controllers don't create power. Let me put it this way, energy generation by the panels would be the same in both scenarios hence overall power (assuming low light conditions). The difference should be in output voltage and current, not overall power (again, assuming low battery charge). My understanding is, the greatest difference would be while trying to charge a nearly full bank under low light conditions. No harm meant, just clarification . |
Re: Solar Energy, A Complement To FTA by chris81964(m): 11:30am On Jul 31, 2016 |
Saipro: No offense or harm created. I highlighted the differences between pwm and mppt controllers. The reference point was the post by @dreamflygn. Two kw in panels and two pwm controllers. |
Re: Solar Energy, A Complement To FTA by Saipro(m): 12:09pm On Jul 31, 2016 |
chris81964: While not fully understanding you, I admit to distrusting the twin PWM setup. Not that quality of PWM in the least. I'll bring up my point later under clearer examples. |
Re: Solar Energy, A Complement To FTA by DMerciful(m): 12:50pm On Jul 31, 2016 |
The mppt is designed as a DC to DC converter hence excess voltage can be converted to current at the output of the controller. In order words, the efficiency of the mppt which is way higher than the pwm controller makes the difference. Saipro: 3 Likes |

chris81964: I agree with you the price is on high side but you pointed out clean installation hence my opinion. I did not want to critisize but merely point out the issues with the installation Not many people realize the modern inverters like schinder or SMA are different utilizing AC coupling compared also to DC coupling only , and by not using this functionality the advantage of using a such a inverter is lost . F.y.i. I am using a cheap but reliable china made gen controller with home hooked system to switch on my 5 KVA gen based on time of thh day and battery condition cost me less than 100 USD total plus cabling . I have modified my system to avoid the small gen going to house or inverter by coupling the output of gen through a 3 KW DC power supply set at 54.3 V feeding into batteries effectively isolating the critical parts of my house from NEPA . |So my system functions exactly reverse of that you have designed NO changeover at all infact no interruption to power unless the system is taken offline for maintenance. in such a case I by pass the inverter circuit to grid /main gen by using changeover cicuit wbr Anil 4 Likes

Re: Solar Energy, A Complement To FTA by chris81964(m): 2:37pm On Aug 02, 2016 |
pranil: The changeover in our system installation is used only if the inverter is needed to be taken offline. Your system and the work you have done is impressive. The inverter that you use has an auto gen start function. |

Re: Solar Energy, A Complement To FTA by pranil(m): 12:52pm On Aug 03, 2016 |
Barezzi: You cannot do AC coupling with Grid Tie inverter. For one it is illegal currently till NERC releases Net metering regulation and grid code for distribution is updated( atleast 3-5 years away) . Hybrid inverter with SOLAR or battery priority is your best bet . I tried to sketch something very fast see if it is legible . I am always updating my system to play with it . Apart from the main equipment I do have remote monitoring of inverters , Remote AH display, Small generator power quality ( V,F,A,Pf,t ) etc. so check the performance. My next step is to take the remaining 1 KW panels to roof with separate CC . Waiting for the aluminum prices to come down. The only mechanical component is the ATS switch and generator - I use the ATS to supply the optional load like washing machine or dryer in case of emergency ( most of the May and june) which are 2.5 KW each . Please let me know what you are trying to supply and I can suggest a optimal setup wbr Anil

Lovely setup Pranil. Been tinkering with my proposed setup, and finally came up with the attached. I have no plans to sell to the grid or go fully off grid. Supply to the 2nd essential load panel will be controlled by my battery SOC. Have a look and lemme know your thoughts.
