That could work, I'll set it up and let you know. Tx for the help.

Give the courier 3 Axperts to deliver on collection and I'll throw in the 3 new clones or clowns

Would not know, came home saw it was in bypass mode don't want to go into inverter mode. They wanted to sell me a new one again and keep the old one. Assistant is working, can't see anything else wrong and only the green power light is on.

If only, I had a 20 Kva Kipor silent type installed in 2008.

Okay, seems to me that I'll have to scrap the 3 month old 5 kva clones and buy different brand. Wife is not going to be happy this time round. Anybody up to swap 3 new 5kva units for a slightly used 2 year old quattro?

The first one was replaced by the insurance. The next one failed after a power failure and the gen ran. It stayed on bypass mode. CA quoted 47 k for repairs which I still can't believe. To me it seems like the changeover relay might be faulty. Insurance said that the unit was still under warranty. I just lost interest in trying to fight and the shipping costs. My load from sunset to sunrise is around 630 watt. I am still going to rip out the fridge door warmer one of these days.

Morning Mark, Done your suggested tests and all tested between 12.6 - 12.75 after 12 hours of rest. I ordered a Fluke battery analyzer which should arrive today and see what that tells me. Any experience with Synerji clone of the Axpert for the correct settings? Regards R

Morning Plonkster, Serial starts with HQ1539..... Because it was a big investment when I started I actually had the guys from CA overseeing the whole installation for insurance purposes,even when the first unit was replaced with latest one. R

Looks more like a piece of art!

Tx Triplett, I'll contact them. Ronnie

Chris, you can actually make a very neat installation using wire mesh baskets or use the O-line 41x41 galvanized trunking with metal covers. The plastic one tend to look quickly 2nd hand when often fiddled with. I prefer to see and be able to feel the temp of the cables. Regards Ronnie

Hi Mark, Would you suggest what each string of 4 batteries must be connected to its own MPPT? Each of the strings then connected together on the two bus bars and from there to the 3 inverters? Must I then divide the 27 solar panels between the 5 MPPT's? Regard Ronnie

I must say, my experience with Victron inverters and after sales service is horrific at best. Also the agent close by closed down. I still think it is one of the best products on the market but maybe a bit sensitive for Africa or for me. Both were sent in to CA and the repair costs was about the same as buying a new one. The fact that I was unable to source the boards I needed to repair it myself did not help much either. That is why I just decided to stop trying to get the best and go the el cheapo route. Can buy 10 hybrids for the price of the quattro units. So they are sitting in the store till I buy a boat, got the anchors.

Tx Pilotfish, I am going to try what you suggested and see what happens. Hope that batteries are still fine, don't want to fork out 75+ K for new batteries. I have fired up my two Victron 150/85 MPPT's and disconnected the panels from inverters. Now the inverters stay connected to the grid and switch between bypass and batteries. Tried to change the settings but my guess is that the inverters does not see the MPPT's pushing 110 amps into the batteries.

Thank you for answering! Triplett I have a BMV 700 to monitor the batteries. These batteries are maintenance free. Plongster, The one Quattro got damaged due to lightning strike statics which entered the system behind all protection. Second one just would not change to inverter mode anymore after running from generator. Think they are too sensitive. I still have the two 85/150 MPPT's. They are bullet proof. They are not the best batteries available and that is why I dont punish them. Never use more than 20% from them. I replaced one last month but the rest are 2 years old with a month between them. I did the conversion from watts to ah to put it in perspective with the total capacity. There is no sudden increase in the load, the BMV 700 would pick it up. I have taken out a string at a time over a 24 hour period and after 24 hours the batteries in the string tests 12.6 v rested. I am awaiting delivery of a Fluke analizer to test the batteries better. How do you suggest I connect or devide the battery strings between the 3 inverters?

Hi everybody, I am new to the forum and in need of help with my system. My system currently consist of the following: 3 x 5 kva Synerji inverters running in parallel. 2 months old. Know it is cloned of something but had not much luck with Victron either, lost two 10 kva units and just had enough spending vast amounts of money. Only still using the bms unit. 20 x 230 Amp Silver Calcium batteries wired in 5 packs of 4 for 48 v and total storage of 1150 Amp hour. Oldest battery 2 years. Never discharge them less than 46.7 volt as per supplier recommendation. Each pack is connected to a H02 balancer which keep the all the batteries balanced within .3 volt. 15 x 255 w 36 v Solarworld panels wired for 108 v facing North This bank is split between two inverters 12 x 255 w 36 v Solarworld panels wired for 145 v due to distance facing West @ 55 degrees due to roof angle. This bank feed one inverter. Even in winter the system is fully charged (57.8 v)at around 11:30 will carrying the household load too and start to float @ 46.7 v for the rest of the day till sunset. The system is programmed to stop discharging @ 46.7 v. My night time load does not exceed 300 ah but average around 268 ah. As you all guessed, my problem is that around 2 am my system switch over to grit power. Any suggestions? Ronnie
