EG4 LifePower4: Proper Start Up Procedure Using EG4 LifePower4 Batteries and More!

hey everybody richard from eg4 here and i'm going to be talking to you guys about a question that's been coming up a lot in the forums uh we've seen it on a few different of the uh posts on there i'm going to show you guys the proper startup order for using the lifepower4 batteries uh we will be using those with the eg 6500 ex model today and i'll just talk about how that whole system is set up and starts up [Music] first thing i want to talk to you guys about is making sure you guys have the right size batteries to the right size inverter we normally recommend leaving yourself a little about a 20 percent leeway there so these batteries they're five kilowatt batteries 5120 watts we would recommend using these with about a 4000 watt inverter so if we've got the 6500 inverter we'd say you should have two of these to run a load um today i'm just going to be starting them up we're going to run a small load here actually a pretty big load just so you guys can see them in action but the first thing is going through the startup order so the light power 4 has a built-in pre-charged resistor and you can actually hear it when it's operating during the initial startup process it kind of sounds like a clicking noise and when you're starting these up they need to have an open electrical connection to the inverter and by that i mean that the breakers or anything you have inside there need to be in the on position so if you have them flipped into the off position it's going to go through its pre-charge cycle and it's not going to actually do anything to start the inverter with the pre-charge so i'll go ahead and give you guys a demonstration here i'm going to show you guys the correct way to do it first so the first thing i'm going to do is i'm going to go ahead and reach back here and turn on the breaker so that the electricity can flow directly from the battery to the inverter the next thing i'll do is i'll go ahead and turn on the battery and you're going to see the lights cycle through its pre uh startup process and then you can hear i you might not have heard on camera but there was a couple of clicks here when i was doing this pre-charge and now the state of charge lights are lit up i can see that this battery's got about a 75 state of charge and my run light is flashing every few seconds that means the battery is in an active status and it's ready to run a load so with that being said i can actually let me turn it towards you guys here turn on the screen for the inverter and you'll see a kick on the screen's turned on the inverter takes about 10 seconds to start up as well we don't have a load or anything on there yet so that is the first step to ensure that you're starting it up properly so what i'd like to do i'm going to go ahead and turn everything off now is i'm gonna run you guys through real quick what happens when you start this equipment up in the wrong order so i'm gonna make sure that there's no charge or anything in here so this time i'm gonna turn my battery on first and right now i've got the rear breaker in the off position so electricity cannot flow through it so if i turn on my battery it's going to go through its pre-charge status like normal and then you'll see that after it goes through that it has the state of charge lights on and the run light on it says that it's ready to work however it didn't go through the pre-charge with the inverter so as soon as i flip the switch i'm going to hear it kick in for a second and then the alarm light comes on this fault will not allow any electricity to come out of the battery it's essentially a short circuit fault and so because of the way that i tried to start it up i had the battery fault out so the way to fix this is pretty simple all you got to do is turn the breakers off give it a second and to continue you just turn the breaker back into the on position and then if i flip this on it'll go ahead and start again let me go ahead and show you that real quick just to show you guys all how it's working here so i can see that this is now in the ready position and turn my inverter back on so for this next demonstration i'm going to show you guys running a load on the uh batteries with these two 6500 inverters we've got these set up for split phase this however is only a 5.5 horsepower uh air compressor it's single phase so it's run off of 120 volt plug that i've got plugged into a load center on the side here the first thing i'm going to do is i'm going to turn on both of my breakers in the back make sure that those are in the on position and then i'm going to go ahead and make sure my inverters are not on i'm going to turn on four of my batteries all right so when i see all four are in a ready status here i've got the lights on all four of these i'm gonna go ahead and turn on both of my inverters now the inverters take about 10 seconds to start up so there's a countdown on the front screen and as soon as that counts down on both of them i know that it's ready to be in use and i can tell that they're in a split phase configuration because the front screen says 2p1 and 2p2 that means split phase inverter 1 split phase inverter 2. so 2 phase so over here we've got this like i said i've got it plugged in on the side here to a load center that i've built into this cabinet and with four batteries we're going to go ahead and turn this on i'll show you guys this operating so as you can see four batteries can easily take the startup voltage and the amperage that that requires to get going uh these batteries are pretty robust so i can actually run this off of two i think if i've done the math correctly so let's double check i've got two batteries turned on i've only got the top two batteries turned on right now all the other four are in the off position so let's go ahead and turn this on so again you can see that that started it up it took the inrush current and then it operated it um one battery i do not think is going to run this i'm going to go ahead and show you guys a demo of what happens when you uh pull too much for a single battery so we've got one battery it's not just the inverter that matters when you guys are running the load your battery has built-in protections to make sure it's not discharging or charging too fast so you need to ensure that you've got enough battery power to run all of your loads as well as the inverters and that's kind of why we have that uh ratio of about 20 uh difference in the watt hours of the batteries versus the watts the the inverter can do so we've got one battery now so even though i've got both of my inverters turned on which can handle 13 000 watts with just one battery if i flip this on you can see it immediately trips this top battery and it doesn't work so i'm gonna go ahead and turn this off again if this happens to you it's very simple to restart you simply turn the battery off wait a second make sure your inverters are in the off position and then you can turn your battery back on i'll turn two of them on here so now i've got both of these inverters i should be able to turn those on without any issues and as you can see they're ready to go again so if you ever do encounter this it's very simple to reset you just turn the batteries off and restart so if you guys have any questions or anything go ahead let me know down in the comments below and if
