Can I put 3 inverters in parallel (2) on L1 and (1) on L2.
This would give me 13K on L1 and 6.5 shared with L2 for 240v loads.
I would try with an amp meter to make share the loads are off balanced to L1. Basically I could monitor the two legs for a period of time one move loads between L1 and...
I have a 6 battery rack, and a 5 battery rack. I am connecting them each to a Lynx distribution module, then the shunt then a distribution module.
The distribution module opposite the batteries will feed 4 inverters. I added a t class 400A fuse to each bank. I also have a cerbo GX to monitor the...
I ordered one. Actually pre order. Need a charger to charge (10) Lifepower4 batteries.
Was going to use 2 EG4 3K inverters to provide 100A charging but this is a cleaner solutio.
Grid breaker in material. I’m 100% off grid no grid input. I haven’t put a frequency counter on it yet but sa gives me 59.99 to 60.01 as frequency range. There are 3 6000xp’s in parallel.
I know that this is the wrong place BUT the discussion is going. I’m looking at building a new room where the electrical panels, inverters … will be located. Every one is using concrete board to mount equipment. I’m looking at putting 1/2 plywood on the wall with 5/8 sheetrock over the plywood...
Fighting an imbalance from the grid, it’s gone. BTW that imbalance is only with your direct neighbors, once you get to the high side of the transformer its a single phase.
The harmonics from the grid are not an issue, if you generation is sized right although you will have harmonic distortion...
Looking at the three phase system all units are tied to the serial pairing com. The paired inverters have their current sharing tied together. The phase that only had one inverter only had the comm connected. The question is this also possible with split phase? All having the comm daisy chained...
I’m just bringing online an off grid system. I have 2 inverters and 2 more to flash with the most current firmware.
The only flickering so far is when the contractor was running his airless paint spraying. This flickering can also be seen when on grid as the pump draws high current when pumping...
I know I can run separate rs232 lines to inverters to monitor several inverters.
Can I monitor batteries on RS485.
I have no problem with the address concept as I’ve worked with 485 for decades but will SA support multiple 485 batteries?
If it does I would get two licenses and use one SA for...
Some geometry?
Span between front to back,
Space between support posts.
From height and back. (Ground to top of cross beam)
I have a similar design 8’ at back and 16” at front. Instead of concrete I was going to use 12’ 4x6 with 4’ in the hole with secure set.
Any thoughts?
Sorry if this is addressed somewhere already. I looked BUT could not find an answer to my question.
Depending on which version of the manual you have in hand the AC Input / Output is spec'd as either 10 or 8 gauged. Which manual is correct?
Thanks in advance.
Also I am bench testing using...
It’s not that difficult. It takes a couple of relays. One relay takes the NO contact from the inverter and opens a 240 line from the inverter out. These two lines go to the Generac. On loss of 240 the generator starts running. When power is stable it provides a 12v signal back. I use that to...
Just a simple question as to the load capability of the ATS. As this thread is about the 5000ES and transformer.
The one listed on SS's website is the ATS 5000T-US. In the product data from Growatt a ATS 11400T-US is also listed...
The Lynx shunt is just a fused shunt, that speak VE.can and if for the lynx distribution.
you can continue to use the smart shunt for both or get a 2nd, one for each bank.
I know the technical pro's and cons of the question I have, BUT what I am looking for is opions as to which way to go.
I am looking at rack mounted battery solution like the EG4. I am looking at starting with 6-8 units (30-40kw).
OR...
What many always forget that time = money. DIY batteries are a great idea, you can repair them when the BMS dies. but what you save in $ is so minimal over buying EG4's or other rack mounted batteries that it is questionable economics. I am looking at the Northstar batteries because there is no...
I’m building an off grid setup.
I have a generator that will fire up on a contact closure (2 wire start)
I have 12 Lifepower4 batteries in two banks 60Kwh of battery.
I have a Chargeverter that I’ll be hooking up.
Can I leave it connected to the battery bank permanently so on low SOC, I’ll...
Can I use a generator interlock on my entrance panel.
I want to use this for the entrance.

A shunt trip breaker has a trip coil off the side of the breaker. All you have to do is energizer the coil (depends on the breaker config) I use 240V from the inverter out through a relay. If it is a DPDT relay you can use the contacts you need to do this. Once energized it trips the breaker...
I’m looking at aluminum bus bars 0.625 x 1.75. From the cross section I should be good for 580A.
I can make two bus bars 36” long for around $70 if I used copper for the same capacity same length it would cost me $350.
Would an inverter generator for example a HONDA EU7000 provide a more stable power source if you want to use an inverter with a Genset?
I was looking at using 2 of the 48V chargers from signature solar in parallel to charge batteries off the genset.
I worked in the hydro industry and once the breakers closed the freq was tied to the grid. Your only freq issues occurred in black start mode. Off grid you are the time base for a lot of devices. To be off 2 seconds a day your freq would only need to be off by .0013888 HRZ. Its not much but...
I know using strut to mount PV panels works good, but I’m wondering if anyone has mounted inverters with them.
I’m looking at mounting 4 inverters, one as a battery charger from a genset and the other 3 as off grid.
I don’t mind using hardi board as a backer but usually the enclosed would...
Using the Lynx distribution system you have a 1000A busbar system.
I have my battery banks on one side of my shunt and inverters and charger on the other side, nice and clean. I made inverter cables all the same length and battery bank cables all the same length (wire gets expensive).
I bought 4 of these breakers but changed the way I was connecting my system. They have never been used.
Two are in original boxes two are open.
230.00 for all 4 shipping included to lower 48 states.
Link to breakers
I don’t have one to look at. If the are at least 4 support (isolation supports from rack) I should work but if there are only three …..
Can anyone verify. Cutting and drilling and tapping new holes for cables is not a problem, the mounting is.
The meter entrance panel has eight breaker locations. (4 if all are 240). I want to interlock the top right location with the 200A main breaker. By doing this I will be completely on grid or off grid. the other 3 (240V) breakers will be my A/C compressor (feet way), my dryer (on other side of...
Instead of using the 100A contactor what about using a breaker with a trip coil.

I just ordered (4) 10AH batteries for the bench for testing. It should work for what I need. The question is can I provide 200+ volts DC to emulate solar cells for testing???
I have (3) 6000xp inverters in parallel.
I have the dry contacts on inverter 1 to start generator at 20% SOC and off at 75%.
Now to the question I have. I have two water heaters in series. The main house WH is a heat pump water heater. The second is a basic WH. I want to turn the 2nd water...
I have been refining a design for a while and would appreciate suggestion or criticis.
Several directions.
I will have three SPF 5000 ES‘s being fed into an inverter sub panel. This panel will have an Autotransformer attached to it. I was thinking of using the 100A Victron autotransformer. It...
I had similar issue with this cold snap. System shutdown low SOC. 8 of the 10 batteries came back and charged ok. 2 are basically dead. the come up flashing red with an alarm. I broke them out of the battery bank and put them on the 18A charger but they will not charge.
hopefully SS will get...
But if we’re looking off grid 50% of the issues go away. Mind you there are still issues but most can be engineered not to go away but to have a safe system. That’s what this whole discussion here has been about even though it has gone off topic like the movie “UP”. —- “squirrel “.
I have a SCADA package “Ignition” collecting and displaying telemetry from the inverters. I can easily use it to control a contactor for the 2nd WH.
I could not find if I could use the contacts independently when in parallel.
I wanted to use a Generac PowerPack 7.5kw to provide power to a battery charger for an off grid system.
But I found this in a FAQ comment on Warranty.
What constitutes a voided warranty?–
The following installations will void the warranty on an automatic standby generator: *Generators used...
That's why I am bouncing this off of others. There is NOT a whole lot on the Victron AT. I originally was going to put (2) SEAUTO AT's in but as I always like to keep things simple I thought if the Victron has more capacity use one instead of two. If it's only 100A pass thru using the same...
Has anyone used this one.

I was going to use two 30A chargers in parallel but this will be cleaner BUT expensive.
