Fantastic features! victron is certainly on a different level of premium and with all these features it's definitely a wish to have but I will need multiple kidneys like you  For now make I dey manage my MPP GK NiyiOmoIyunade: 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. |

earthrealm: 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 , thats enough energy to keep a decent freezer powered 24/7, as an equivalent hybrid would gulp less than 30w idle consumption. 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  |

NiyiOmoIyunade: I assume you are running EmonCMS locally and using the dataplicity reverse SSH tunnel to view your dashboard remotely? That's correct Lucky you with this approach as you can have so many data feeds on your dashboard. EmonCMS.org charges me £1 per feed per annum and this without UK Vat levied. I have to choose carefully what I want to host/show publicly to keep hosting costs low.
Good side is I can share publicly to a nearly infinite number of users (currently 2 family members and 3 staff have access to regulate their power usage).
Does dataplicity support more than one user logged in per time? I played around with a few multi user access local hosting options but they were not stable - random downtime needing me to dedicate time to fix things so I ditched them in favour of EmonCMS.org 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 |

NiyiOmoIyunade: With more than 3,000 promised cycles it would need at least a year before one would see any signs of degradation even under abuse. Realistically 5 years plus with normal daily use 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 |

NiyiOmoIyunade: A quiet weekend allowing me to benchmark my home-office energy system performance and evaluate the design choices I made with single phase 15kva vs 3 phase 5kva
Picture 1 - Battery @ 100%, Peak loads running and Solar just matching house loads
Picture 2 - Earlier in the day - Battery @ 100%, Base loads running and Solar just matching house load demand.
Picture 3 - Couple of days ago - solar production at historic peak - sustained for like 12 minutes.
Picture 4 - Couple of days ago - testing new energy dashboard in the cool of the day - 6pmish - low solar, aiming for peak loads and testing out Victron's power assist and AC current limiting engineering miracle - basically using a 5.5kva Diesel Gen to drive 9kw+ of loads - the inverter was set to take only 4.5kva from the Gen and source the balance from the DC bus (battery or solar). Mix everything AC and DC sources together thoroughly and spit out combined power to the loads 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. |

meine: Meristem is very expensive and not good for jijo. Good customer service though.
Standard fees is 1.8% to buy and 2% to sell. 1.35% to buy if you negotiate. I believe the op asked for broker's service charge which is 1.35% the rest of the charges is not for the broker and I believe will be the same with the rest. A typical breakdown attached. Nevertheless they are indeed very expensive

Am thinking of going for it by next week, though someone was trying to discourage me that it has factory AC issues. Waiting for your response please
I got it new. It came from the US. I have not heard anyone that use that same model complain of factory AC issues. It's 2.65 million. The other cars that came with mine are 2010 and 2011 corolla which goes for 2.75 and 3.15 respectively. I think they are still available. I have got the sports edition of 2010 corolla with 87k miles on the way to naija from USA. Ping me if interested

ceaser: I think you should be able to power those two appliances with your 850 watts inverter. 850 watts will sustain a peak of 1700 watts. If you start the freezer first and allow it to settle, you can then start the fridge few moments later. The highest continuous consumption of the two gadgets together shouldn't be more than 250 watts.
The inverter may sustain the two if started at different times, but definitely not if started simultaneously. That could work initially but as time goes one it won't; the compressor comes on and off periodically hence the surge on both may occur at the same time. |

NiyiOmoIyunade: Please is there a particular reason one would want a separate charger and not utilize the charging functionality already bundled with a decent inverter? There is no major reason for that unless the inbuilt charger is not doing as much amps as required. So if my bank is 400AH and my inbuilt charger can only do 30A, adding an external one to support will be helpful to the battery. The other reason I can think of is for certain lithium BMS that does not wake up with solar charging when they trip due to cut off voltage. An external charger will be required to jumpstart the BMS so the inverter can come alive. Edit: I see this has been dealt with |

ceaser: Thanks a lot
I think the LED bulbs will be better pegged at 5 watts per room + 5 watts per bath and toilet. That makes 10 watts per apartment and 200 watts total. If more economy is needed, the bathroom lights can be pegged at 3 watts which will give 8 watts per apartment and a total of 160 watts for the 20 apartments. On the assumption that all lights and charging ports are used (which is unlikely), 200w plus 100w from charging points makes 300w and about 4.2kwh (14hrs battery backup) which is still within your capacity. However I will suggest 48v 150AH and 200AH if you have large budget.  By the Felicity 48v 5kva, will it be bad if the 60 amp MPPT or it can still go as an extra addition? (I really won't like putting all the eggs in one basket of Felicity or one basket of another MPPT CC. The reality is that if the felicity goes bad, the external MPPT is also useless as well as you will still need to get an inverter. So I don't see anything wrong with using the hybrid for the solar completely. Based on your load, I also think you should be fine with 9x320w considering that lights won't be on during the day, pushing things to 12 units is just to cater for days sun is not smiling. My setup is 280x9 and I generate up to 8kwh or more daily (if needed) with same battery capacity as yours (though my nominal is 25.6v which is about 5kwh) and I think it should be same norminal with yours if it's Lifepo4. My load is way above yours during the day and my battery is 100% by most evening In summary, if the 48v 3kva felicity can accommodate 12 units go for that, if it can't go for 9units but if there is funds and you want to do the 12unit then push things to 48v 5kva which I am certain can accommodate 12units comfortably. Alternatively @Valto put a 3kva high Voc inverter for sale, if you can ensure no shading on the panels then go for that and put all the 9 units in series. |

ceaser: Private hostel:
✓ 20 rooms self contained lighting point (approx 40 lighting points) ✓ Pumping machine 750hp (better it is run during daylight hours) - controlled by float switch and a timer so programmed. ✓ Charging points in the rooms (1 usb AC socket per room) giving around 5 watts x 20 rooms = 100 watts.
I'm yet to determine insolation and sun direction and also the distance from roof to potential site of inverter set up.
My proposal:
• 60 amp MPPT (1 unit) • 10mm duo core • 320 watts mono panel (12 units) to be in 3s3p • Felicity 48volts 3kva pure sine hybrid with 60amp MPPT to take the remaining 3 units of panels. • 48v 100amp Lithium battery
What d'you think sirs? You did not indicate the wattage of the bulbs which will better inform on whether 4800WH will be sufficient backup. That said I don't think there is need for the bold, get the felicity 48v 5kva instead and run 3s4p instead, if the 48v 3kva felicity can do 3s4p then that will be cheaper option. |

If the company can lie about the capacity of its lithium battery, [b]it shouldn't be difficult for them to lie about the capacity of their inverter[/b]. Special thanks to @Ojeysky for helping me with getting the data from the inverter using solpiplog. Lol.....but really their inverter is not that bad and they seem to have good warranty as I have gotten a replacement before. When I used the 3kva/2.4kw hybrid version, I pushed it above 2kw and it was fine, just the heavy fan noise which is expected. |
