NiyiOmoIyunade: This is a fantastic feature, so you can set the max power the inverter should get from your AC (Gen)? and then it takes the rest from other sources? Otherwise how does the inverter determine it needs to take 3kw from your Gen (AC) source? MPP does mixing with solar power and AC but you can't set the max power it should take from AC it does that by its own algorithm dependent on how much sun power is left after/while charging the battery. |

NiyiOmoIyunade: Yeah, very valid point. Transformerless inverters have an achilles heel..very fragile.Mpp readily stood up to the challenge for Ojeysky. Hope phocos and sorotec would do same when the time comes. @ Ojeysky, Valto is the reigning sorotec king for now, perhaps he can chime in, Kiekie i think is just selling and not using phocos, so cant really tell us much. I like the inbuilt wifi logging and streaming capability of Sorotec, phocos promises something similar. Hope that famous youtuber would do a comparism some day. Mustpower and Easun are also not doing badly in the hybrid biz. Would surely switch to a hybrid when am upgrading.My trusted 4kva mustpower transformer based inverter is gulping over 130w, by just being on ![]() 2 Likes 1 Share |

NiyiOmoIyunade: Indeed, I put in a BMV into the mix about 4 months ago and I am still less than 60cycle. It's going to be a long wait to see any degradation. I may decommission it soon though as I am planning my final bank upgrade for many years to come (hopefully) - not happy that the sun power is wasting once the bank is full, need to store more energy to cater for days sun is not smiling |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 2:26pm On Aug 08, 2020 |
NiyiOmoIyunade: That's correct
It does but at a cost, but why will you need more than one user? I am using the free option which gives me limited daily bandwidth to access my emoncms web interface remotely. When I am home I have the option of using my home WiFi instead which does not count against my dataplicity bandwidth. I prefer logging locally as it's a sure way that removes possibility of network downtime associated with remote logging |

earthrealm: What! That's massive, here are figures of my 3kw MPP: 1. When just on and not powering load(idle) 18w 2. When powering load through AC only 30 to 40w 3. When powering load through battery only 40 to 60w when less than 500w of load and up to 70w as load increases. 4. When powering load from solar 30 to 50w 5. When powering load from AC and charging from solar - no consumption That said the the xtm and victrons have better power efficiency but I rather spend the extra cost on more battery bank to cater for higher consumption and provide more capacity to my household +extra Board ![]() 1 Like 1 Share |

Yup! All Victron MultiPlus & Quattros support these advanced features natively. You can set precise AC current limits on both AC Mains and AC Gen inputs and dynamically even adjust the limits of one input on the fly from VEConfigure or VictronConnect or GX Device (with a GX device you can even adjust the AC current limit over the internet) Having set your AC current limit, you can then set PowerAssist boost factors (allows the inverter to borrow power from the DC bus to assist a Gen or Mains supply and prevent it from being overloaded). Thus a 2.5kva Gen may power over 5kva of loads with no stress on the gen - Victron afficionados catchily call this "Small Gen, Big Power" Once the two above are set, then you still have a Dynamic Current Limiter that allows the inverter to smoothly transfer loads to a Gen AC input so the Gen sees no sudden shocks - this is much like how inverter ACs ramp up power slowly. The inverter absorbs the power difference and passes it to the Gen small small up to the user set limit. In my case I am taking about a max of 4.5kva from a 5.5kva Diesel Gen - the Gen takes on the loads slowly over like 15minutes and doesn't even realise it is loaded 80% - it just chugs along happily. The last feature is "Weak AC Input" - if you set this your inverter will take power from the worst of supplies - low frequency, low voltage, poor surge response and still charge the battery successfully but you sacrifice some efficiency as the power factor derates. These are the features that make a premium product like Victron worth the extra expense - they do easily and reliably what other brands cannot even imagine to begin to do - again this is superior engineering as at today - in the future it may become a normal standard feature of all inverters. ojeysky: 1 Like |

Although I have the Victron and Fangpusun BMVs, I ditched local monitoring for the more robust reporting features available via a GX device. I had to choose the Venus GX (no screen) as only that device in the Victron world had the required number of ports to connect 4 CCs, 2 inverters, smart managed battery and bring them all under smart management and BMS control. To my chagrin, Victron released the CerboGX designed to robustly connect multiple devices less than a month after I already bought a Venus GX. The lack of a display screen motivated me to develop proprietary software to interface with GX devices, Battery & Tank level monitors, Currrent and Weather sensors and post directly to EmonCMS and other dashboard sources bypassing Node Red, SolPip... and other similar crutches that the average DIYer would use - this allows one to flexibly monitor and dashboard any and every metric of interest - if your device outputs a signal over RS232, RS485, TCP, Modbus, MQTT, DBUS, chances are high we can catch it and dashboard it for you. The current house dashboard updates every 10 seconds - one could point it to EmonCMS local or public or PVOutput.org or a number of other sources just at the press of a button. Right now it outputs to a screen at the office and 6 phones all over Lagos. Whether I am at home or on the road, I can see a view of whatever my power system is doing as at 10secs ago - this works seamlessly regardless of location and number of connected users. More importantly I can benchmark the various sites I maintain either via the Victron VRM portal or EmonCMS - I can spot issues and signs of trouble early. These are the justifications for multiuser accessible remote monitoring - customer support, performance benchmarking and just basically keep updated on the status and health of your system. When I have the chance I want to add early morning email notifications that contain that day's weather and solar insolation forecasts and yesterday's performance summaries. ojeysky: 1 Like |

NiyiOmoIyunade: Exactly, although full off-grid users tend to enjoy the most benefit from the fragile hybrids. No phcn high voltage or low voltage wahala. One of My client has been running off-grid 9kw pv with a 5kva axpert almost clocking it's 4th year with no inverter damage for once. I also integrated a vill power to handle the heavy loads when needed. Both have been running smoothly. I only retired the vil power and changed to victron this year as a kind of partial upgrade. 1 Like 1 Share |

Certainly a good buy and meets the specification. Though I think it's sold at 500k now....if you are interested, mine will be available for sale in near future (when I get to do my planned upgrade) |

NiyiOmoIyunade: I think I may have misunderstood what you meant by multiuser, thought you meant shell access to your server (in my case pi3+), my emoncms can indeed be accessed by multiple number of users home and remote. The only limitation I have for remote access is data due to using free version of data duplicity though I have never hit my daily remote peak, but I guess if I include my emoncms link on my footer for folks to take a look on live data, I will easily hit that limit daily. I also log at pvoutput and that is linked on my footer I look forward to seeing your arsenal of gears someday, I can imagine what it looks like. We na baby DIYers for your stable o ![]() |

Gradually winding down on DIY and experimenting o my oga. E be like say I don reach where I dey go with this PylonTech stack. I have been giving out assorted inverters and gadgetry that pushed me through these many years. I have some 12v 200Ah batteries in very decent shape available for sale and should put these up soon. We are all on the journey of continuous improvement and the good thing is all that we have learned cannot be taken away from us by God's grace and we shall definitely keep improving as well. Business needs are making me focus more on Lithium batteries vs lead acid and also higher end inverters with proven track record. Whatever offerings will stand the test of time and give solid value to customers, you will find me there. ojeysky: 3 Likes |

Finally closed the day at 59KwH solar harvest and 49KwH energy consumed by appliances during the day (see pic 2 of 2). This was a stress test passed in flying colors - I do believe the PV array is rather oversized but it gives the assurance to run large loads as if on Mains - this is key as the only backup power I have is a 5.5kva Diesel Gen - no connection to PHCN grid whatsoever - no cables or service pole near me NiyiOmoIyunade: 4 Likes

Very nice! Unless i missed it, can you elaborate on the bolded? I suspect you'd have been better served with a 3 phase 5kva build ![]() A typical Quattro's second output is limited to 50A ac, around 10kw. This means your heavy loads are at 10kw or lower. If higher, do you use assistants to start a Gen to Power Assist? I'm assuming your loads are split into Essential and Auxiliary loads. NiyiOmoIyunade: |
