Re: Solar Energy, A Complement To FTA by duwdu: 11:29am On Feb 19, 2019 |
ojeysky: pranil: pranil is so on point. Also, as with the PCM60x that I currently deploy (which I believe is essentially the CC built into these PIPs) — just as with most reputable CC's — the PIP is designed to wake up once the volt coming in from the PV array exceeds 48 VDC by a couple of volts, for a 48 V system. However, as already pointed out by pranil, it won't do MPPT until the array voltage hits 120-450. In addition, ojeysky, I believe I read somewhere, probably in its own specific manual, that with the 3048 model (which is the specific one you'd indicated interest in,) works with 350 VDC max? But please don't quote me on that - I might just have been looking for more reasons to chose the 5048 over it, lol; instead, I'll advise you consult the 3 KW's own specific manual/reviews on YouTube, if not already. ........

kiekie1: These specific inverters are designed to take advantage of high voltages while pushing relatively smaller currents. Even with two 500 VDC strings in parallel, not more than 30a protection should be needed, so I believe 63a+ breakers will never do the job or trip. Do you or others have 15/30a variants? ........

duwdu: Now I am wondering maybe I should get the MK series instead of the GK as it seem the GK high VOC seem not to be of great advantage? But my concern is that the 3kva MK series only does 1500W solar array while GK can allow me up to 4000W. duwdu: You are right, I saw it somewhere as well but it's stated up to 450 in the manual. I don't think I will have to get to 300VDC anyway so not a major concern for me. Am sorry am not a solar guru, can you educate me on why you eventually went for the GK instead of the MK? Thanks |

Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:56am On Feb 20, 2019 |
zeestone99: I don't think so, he got a 5kva which does not have the 1500w limit on the 3kva version. |

I have a question for the electricity buffs in the house. A friend is constructing an office complex and his electrical contractor wants to install an RCD/RCCB at the service entrance to protect the whole facility (all personnel and devices downstream of the RCD/RCCB) In order to 'improve the speed at/certainty with which the RCD/RCCB could respond to a fault and disconnect the supply', he has already jumpered/connected the Neutral and Earth bus bars in the DB with a 16MM cable - this installation is here in Lekki - while I know this practice of linking Neutral and Earth is common practice in North America and even mandated by their electrical code, I am yet to see it done here in Nigeria. I had raised a similar question previously - what do you think? Should Neutral and Earth ever be linked here in Nigeria ![]() Does this practice help the performance of an RCD/RCCB in any way? The office will also have solar power tied in(where I come in ![]() 1 Like |

Good morning sir, If everything goes well, you shouldn't have a problem. And yes, the neutral terminal is usually grounded at the substation. I would however request that you second verify with a tester that there is no current flowing in the neutral terminal before hooking up the CC. Regards, NiyiOmoIyunade: |

ojeysky: TBH, I'm not a guru either but hopefully the following will address why I chose the GK stable over the MK, as well as the high voltage thingy... First of all, are you referring to the 48V model of the MK, or that you don't want to do 48V, or that it's not offered at 48V? I'll be surprised if any 48V unit is limited to 1500W, so please check again, you may just be good to go. Having said that, my primary reason for going the GK route is the several advantages of deploying up to 450/500V DC when properly managed. Among these, are: 1. The charge controller portion should wake up earlier and retire later - gives more harvest/production time; 2. Much smaller gauge wire (so less set up cost) can be deployed over longer distances between the array and the inverter as the effect of the % drop in voltage will be negligible since voltages are quite high to begin with, giving better amps/yield; 3. Of course up to 5 KW of array at high voltage; this can be further optimized with up to 20 panels (250W @ 37 VoC each in a 10S2P config, for example) on just one inverter as I look to grow with it if its durability holds well. Then there are other things mainly found in the GK series, especially the 5 KW model: 1. Support for Batteryless operation. (I consider this a major factor) ; 2. Detachable display/control panel - for wired remote operation up to 30m(?) away, IIRC; 3. Direct supply to load, even when battery is present; that way one bypasses the inefficiency associated with having to pass power through the battery first to the load even when sufficient solar/grid power is available to directly supply the load; (I don't think this is unique to the GK.) 4. BMS interface is already built in for Lithium batteries; 5. Bluetooth is built in; 6. WiFi interface is built in, although the WiFi Card itself is optional component, which I bought; 6. Latest technology & design from the Voltronic/MPP Solar stable, etc. The main disadvantage I see with the 5 KW GK is that units cannot be parralled. They have to be used separately. Hope those help a little. ........ P34c3 ..... ... 2 Likes |

Thorough and balanced review of features and pros and cons and masterfully done too. The only dissent I may have is when people talk about CC waking up earlier and sleeping later at higher voltages - I feel that yes the CC may wake earlier and sleep later but any amps/watts harvested in the wee hours must surely be very negligible - just my untested feelings on the matter. duwdu: |
