Don't no what kind of system u want or d size of ur load, ur location will determine cost of materials but u can get some items off this thread Lifepo4 battery from Valto Jinko panel, I'm sure u must av notice someone posting that here SPD MCB DB n cables from zeestone Etc guente02: |

Or if d money dey buy mppt with 2 300w cause of future upgrade Gshems: |
Satellite TV Technology / Re: Solar Energy, A Complement To FTA by Jefferyzz(m): 1:10am On Feb 24 |
It will charge it but it's won't b optimal. He won't get anything close to 300w going into d battery. Max e'll get is 145w. Mppt is a DC to DC converter. ie converts volts to amps but ur panel must b at certain voltage b4 this is done. My CC mppt working voltage is 35v. Some 300w panel underload will give like 31v 9a, for a 12v system that 31v will b cut off to 14.5(bulk voltage) n 9a which is like 130w, same thing goes if he's using pwm. But if 2 is in series, mppt kicks in n convert d excess volts. So u'll av close to ur panel capacity. Imagine 9a going into d battery at the same time supply small load on d inverter. If d CC is pwm n it's 12v system best is those 180/190w panel with 9a or 10a isc in parallel. Obnoxious2001: |

Efficiently? Yes but it will charge nonetheless I may agree with the person cause 1. Ure on a 12v system n ur panel working voltage will likely b below d required voltage that's needed for ur mppt to work(thats if ur CC is mppt), so ur mppt will function like pwm Are u using a lead acid battery? If yes, ur battery won't get to float with just 1 300w n u will soon start noticing capacity drop Gshems: |

What is your bulk and float charging voltage on ur charge controller u used to av a sealed lead acid now u own a flooded battery. I assumed u didn't change the charging profile. U series 2 180w(say 36v 10a) then parallel them with 540w(41v 13a). U will putting 36v 23a(828w max) through ur cables(6mm). All these are assumed figure, I no africell don't perform up to the stated capacity. Here is where u should suspect foul play. Ur CC displaying 900w max is misleading I'll advise u get a DC meter to know the true figure If ure using 6mm cable (assumed) n d length is above 10meters. U will experience voltage drop u won't get up to that 36v Check d body of ur battery if there is a c rating written on it. Most lead acid are charged at 10-20% of their capacity. D cable between ur CC n battery too should b 23mm since ure moving 60a into d dem. BlueStripper: 1 Like |

Buy lifepo4 165a or above battery here instead of those lead acid that's inside the 2 list Infact buy all the parts listed here urself den call Dem ova n pay installation fee. U won't get best material with what both of Dem have listed for u eg see pwm CC. U can get 60a mppt for 100k here Get 2 550w panel for 155k each Buy 1.5kw psw sachet inverter here 4 too Buy the time u add them up u'll see uve not spent up to 1.3m with better n quality materials.

Ask ur installer to bring down 1 panel first, check d spec n use the info provided in our previous conversation to make ur decision. Nothing confusing, u fit just pay d installer more for d added stress, it's not something that can't b done. toscotech: |

Series connection - adds up voltage n picks lowest amperage in an array Parallel - adds up d amperage n picks lowest voltage. Use this along side ur CC spec to arrive at d best decision. Check ur 200w panel name plate for d info toscotech: |
Satellite TV Technology / Re: Solar Energy, A Complement To FTA by Jefferyzz(m): 9:08pm On Feb 20 |
The 2 images u sent is 250w of same voc n isc. U can series it. Ur CC max voc is 150vdc D mppt working voltage is 30-150vdc Anything below 30v will make ur mppt will work as pwm so I won't advice putting d 2 panels in parallel. Since ure connecting them in series just look for panels with same isc 8a+ as ur 250w(even if it's 400w eg 49v 8.2a) and make sure ur total voc no go above 150v. toscotech: |

Satellite TV Technology / Re: Solar Energy, A Complement To FTA by Jefferyzz(m): 5:49pm On Feb 20 |
If the voc of both is dsame u can parallel with very little loss(10-20w) If the isc is dsame u can series. Ive tested this with 545w n 460w both av voc of 50 n 49.6 But b4 all this decisions can go, u need to put ur CC into consideration eg ur mppt operating voltage range, max voc, max amp etc toscotech: 1 Like
