mank1234: In what way my brother?. Cc is the only limiting factor, for a 12v, you would hv to run multiple cc, if you want to have panel array above 700w and still use 12v inverter |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 9:43am On Jul 05, 2020 |
harizonal123: U loose mppt advantage, since ur inverter is 24v, the vmp of 250w panel in bright sunlight wud be about 26v or so..not enough potential difference to push the amps and ensure proper charging. In one of my setups i have 3s2p 280w..and incoming voltage vmp is usually about 76v in bright sunlight...and upto100v when its raining. 2ndly if your cable run is long..you would need very thick cables to carry the over 44amps without suffering massive losses.. 6p is a no brainer, only a jjc or a rookie installer would even entertain such a thought 1 Like 1 Share |

earthrealm: For a 60A cc that support 12v, 24v, 36v and 48v setup, is it not the inverter that will determine what voltage you run the CC? If the inverter determines the voltage you run, it then determines how many Watts the panel can be since the CC cannot go beyond 60A. If your inverter is 12v, you'll run less panel than you would on a 24v inverter using the same cc. If you are to run multiple cc in order to achieve same wattage at lower voltage, then it's not the CC that determine the wattage but the voltage of the setup which is dependent on the inverter. 1 Like |

ceaser:Stopped charging until I have to off and on the breakers. It happens every time the sun is very high. |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 11:09am On Jul 05, 2020 |
ojtech8291: Haha..your connection is wrong...likely overloaded the cc above its rating |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 11:20am On Jul 05, 2020 |
mank1234: Lemme paint a scenario. We may be swying same thing but differently. Half full and half empty cup You have a 12v 3kw inverter...yeah the americans n germans produce such .this has been serving you well over time. Now you wan to add solar panels.you have acquired 2kw/3kw array ... You could either get 3 to 5 units mppt CC, or you discard your beloved Magnum inverter, get a 48v inverter and go for a single 60amps CC,. Taking this decision, a lot of factors would hv to be considered. It wudda been a simpl3 decision if the inverter in question was a cheap 12v 1.5kva chinese inverter, but again most owners of such cheap small capacity inverters rarely exceed 1.5kw panel array |

Re: Solar Energy, A Complement To FTA by dapsyra(m): 11:25am On Jul 05, 2020 |
ojtech8291: Your CC is probably going into protection mode when the sun is very high due to one or more of the following scenarios. 1. Over Temperature. The temperature of the FETs have gone above the safety threshold due to continuous operation at maximum power 2. Over Current. The output current spiked above the rated capacity for a sustained period 3. Over Voltage. The input voltage rose above the rated MPPT voltage You need to rejig your array to avoid these issues. 1 Like |

Why I may continue to get sunfit panels if I can find them. That is from a 2.25kw array, what else will premiums do than this Note that it could have gone beyond if not for BMS limitation 2 Likes

earthrealm: You mean one can connect multiple CC to one battery bank? |
Re: Solar Energy, A Complement To FTA by dapsyra(m): 12:52pm On Jul 05, 2020 |
spartacus11: Yes, you can connect multiple CC to one battery bank |
Re: Solar Energy, A Complement To FTA by ojtech8291: 12:55pm On Jul 05, 2020 |
earthrealm:Yeah... The VOC of the series connection is a bit higher than that of the CC. |
Re: Solar Energy, A Complement To FTA by ojtech8291: 1:01pm On Jul 05, 2020 |
dapsyra:It should be over voltage because the VOC of the series connection is little more than that of the CC Maximum input voltage. Maximum CC is 70V but the panels are 2S is around 77.6V. 1S4P will result to a lot of voltage drops. The only solution now is to change the CC. Thank you. |

ojtech8291: Hahaha. You are very lucky , that you didn't burn the cc, you were told b4, ojesky encouraged you to risk it |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 2:07pm On Jul 05, 2020 |
ojeysky: Try and beat this. 3s2p 280w x 6 yingli panels @ noon Total 1680w installed capacity...harvest 2035w, it even hit 2045w..but went out b4 i could take a picture. Next step would be to verfiy this readings with a clamp meter, cos i had about 34.6amps coming in @ 57.6v or so 1 Like 1 Share

earthrealm:Lolzzzzzz...The CC has very good protection but very bad in terms of array manipulations. It is called solarmate charge controller. Who has used it before? |
Re: Solar Energy, A Complement To FTA by earthrealm(m): 3:08pm On Jul 05, 2020 |
ojtech8291: Throway that useless CC, its a glorified pwm, masquerading as mppt. Go find powmr or makeskyblue mppt cc...e no go pass 40k/45k 12v _ 48v 60amps mppt |
