Can you use a SW4048 or XP without the control box?

Most AiO struggle with surge current, so you may have to go way oversize for starting, and they have high idle draw. This means they consume more power even when loads aren't being supplied. For Chinese AiO, it's about 40-50W continuous per 3000W of inverter output. 50W continuous is just shy of what it takes to power a residential fridge for 24 hours.

gateway is a kind of mandatory option,

I was planning on having a small...say 8 panel array and paring up a charge controller. The purpose was to be able to run the freezers / Fridge well pump during long outages. Is charging turned on by default, I guess the appendix states this like the user above says. Honestly, a AIO would / could be a better solution but they just don't have the reliability record.

Idk if AC charging / passthrough is enabled by default. But the main problem would be it probably comes with lead acid voltage settings by default.

Probably just have to consider buying an insighthome as well as part of the total cost of any Conext product.

When I bought my SW4024 and SCP back in 2016, it seemed like it was a great choice. Schneider then said they were discontinuing the SCP soon after I installed it, to be replaced by the Gateway. Then they discontinued the Gateway. Meanwhile their business model was to cater only to professional installers, and DIYers could go to hell. When I switched to LFP batteries I wanted to set the charging / abosorption voltage from the SW4024 down to something like between 27.6V and 28.0V, but it wouldn't accept anything below 28.8V. Can't update the firmware to it, so I'm stuck. Good thing we almost never have to charge from the generator.

Since then I've helped spec and install two Victron systems. No doubt I would have gone that way for our cabin the first time if I knew how consumer-unfriendly Schneider is.

Is there a comparative Victron inverter that has split phase? The well is 220V. I don't want multiple inverters or spend a huge amount which is what make the xp or sw interesting.

There is a Multiplus 2x120V that has split phase 120V, but it's limited to a 3000VA model, so it depends on if that is big enough. Otherwise it isn't difficult to set up two Multiplus or Quatro inverters to give you split phase.

No. Victron inverters are either 230V/50Hz EU versions or 120V/60Hz North America version. You can use two identical 120V units to form 120/240V split phase. You can also reconfigure 230V/50Hz EU units as 240V/60Hz for single phase 240V. They can be coupled with an autotransformer to produce 120/240VAC split phase output.

There is a Multiplus 2x120V that has split phase 120V, but it's limited to a 3000VA model, so it depends on if that is big enough. Otherwise it isn't difficult to set up two Multiplus or Quatro inverters to give you split phase.

2x120 units are strictly 120V inverters that intelligently handles changing AC input between 120VAC single phase and 120/240VAC split phase.

It can't provide 240V in any way unless it is passing through the second leg of 120/240VAC split phase INPUT power.

Wow. Good to know. I figured blue-you would have answered before me, and when you didn't I went with what I thought I knew. I guess I only skimmed the info when the 2x120 came out. It certainly sounded like they were targeting people who really need an inverter with 120V/240V split phase. It's either a bit of false advertising or (more likely) me not reading it completely.

It's specifically for 50A RVs. It's a 120V inverter.

If supplied with single phase, it passes through the same 120V to both legs of the panel like when connected to 30A shore.

If supplied with split phase, it feeds both legs to the panel and can charge from/powerassist on L1. L2 is strictly pass through.

If boondocking, it supplies the same inverted 120V to both legs.

Thanks. It's a shame that they didn't allow a serial connection with some software on a laptop or something. I wonder what the defaults are, I'd assume some batteries from SS or comparable would need to be tweaked thus requiring a $400 extra piece of hardware. I'm still planing on a whole house setup at a latter date but wanted to get a inverter to run the essentials,fridge / freezers & well pump. Schneider was a easy pick for this task due to their rep. I just hate the idea of spending $400 just to set some stupid settings once.

It's also required to diagnose any issues with the system, for BMS communication, and communication between multiple Schneider components.

The SCP is still available for CSW and XW. The part number changed and it is available from Xantrex. For about $300 you can control everything except some of the more advanced settings in XW pro. Will work fine with XW+ CSW and old XW greaybox. Must use 809 - 0922 only! The other similar number is for xantrex Freedom inverters.

Xantrex System Control Panel (SCP) 809-0922 for Schneider XW and SW Inverter/Chargers (809-0922)
