That's why always recommend to people to go with a transformer base LF inverter. One of the guys I know that works for Victron did a nice video by testing a mecer unit against a Victron on his testing scope. Massive difference on the AC output side.

@handsome @pwatts I think comes down on the inverter, it's High Frequency inverter and they are a bit famous making noise. HF inverters got a very high THD and operate between 20 000 and 100 000 Hz. That's why I always op for Low Frequency inverters. I'm running 2 Low Frequency inverters that...

60 or 70 year old equipment? Russia is a bit of state with the stuff they have. Israel ground equipment infantry is way more advance. They not going to play around.

@Andre Vermeulen , daai 3 woorde klink baie bekend......

It's always interesting thing, new people joining the forum groups, first thing they do is, they complain or they take on the big guys with the first step in to the door that's on the forum for years and have experience. :ROFLMAO:

sjoe, some stubborn people that join the group.

Just heads up, there is allot of scammers now that sell panels that they change the stickers at the back and say it's a "450w" panel and then its rated at 360w or 380w . Here is a post on the other forum where someone was scam 450w fivestar solar panels

I'm running a 10kw array on my roof. 435 x 9 on my North side and is string that I can add more panels. 335w x 9 on the East side and 335w x 9 on the west side. I'm planning to add extra 7 on the North side because this will help more in the winter side and I can add more loads on the inverter then.

Always try to get close to inverter rated output or say 70 to 80% and if you got the roof space, stack it full if your pocket allows it. Why I'm saying this is, say you got a good sunny day, then you can charge the batteries and get them full as quickly as possible, especially like the weather...

OOOOOO wag, dan is ek kort op sy hakke, Dan is ek nog nie hetemal agter nie :ROFLMAO: Offgrid die kant ook. Het Jan 2022 laas krag gekoop.

Like DACman mention, you need HV battery for the ATESS unit. 30/24 HV is about R175 000. There some other brands of HV batteries but it's still going to cost you some money.

ISh!!!!!! ok, dit is n groot setup. EK begin op hou tel toe ek oor 42 panels tel. dink daar is oor 50 panels daar op, en ek het gedink ek het n groot setup maar hulle wen daai een. KOn jy onthou wat hulle op het in die garage.

Af in die straat van jou, IbIs st en Egret St, daai ou het mother of all system!!! Hy het vrek baie panels op. :ROFLMAO:

@2wice what brand inverter do you have? If it's one of the bigger brands like Sunsynk and Victron and MLT, you can adjust it to charge at full amps, Lithium batteries charge really fast.

Looks like you guys have a blast of a time @achim and @BJ . Told my wife I think our next holiday trip need to be via Munich to go to the show.

Going to throw in my R100 "not 2 cent" into this. Love it when people use the word in "Off Grid" when going solar and they mention a 5kw inverter and one battery. That's not going to float, only if you rowing in a one man boat in the ocean. If planning to op to go that way, rather stay connect...

I always recommend people to go for brands that is supported good in SA where if you want to add battery in a year or 2 that you will still get them. One local company locally discontented one of batteries because they replaced the series with there tower batteries, allot of people not happy...

Yes, the Phoenix range is build for off-grid setup and for ships and campers/4x4 vehicles where the batteries get charge by the alternator or solar controller. The bigger units like the 3000va can take AC power on the output side of the inverter to assist with charging the battery but you need...

@Family_Dog The Phoenix is full off grid inverter, don't have a AC input for charging. @silversonic you need to remember to get a charger for it.

@silversonic go the 200ah. The bms will allow a bit more discharge power. I picked up with my father setup that the 12v 3000va Phoenix kicks the BMS in protection mode if it pulls passed 70amps discharge and if the mppt go's passed 70amps charge. We order another revov 12v 200ah battery to...
