Am I the only one who imagined the Blendtec "Will it Blend?" guy at 9:57 smiling and saying "Don't breathe this..." ?

I've had an Air 303 for over 25 years. It's a 12V unit bought when PV was still $6/Watt and pursuing alternatives made sense - obviously no longer the case, like axis trackers for PV. The 303 was the design the AIR 403/30/40/Breeze/X are all based on. All wind turbines have to employ one of...

Thank you for posting this, glad it worked out. I feel like those of us with XWs are getting good at voodoo...

Under Configuration / Reset / and then "Reset All Settings to Factory" is what I was referring to with starting from a clean slate. Might be worth the time to take notes on your settings before it's wiped.

Those APC UPS are as you know set up to use VRLA batteries. They are expecting a voltage/current relationship and health consistent with lead acid chemistry, and they periodically test that the battery is within serviceable range. (Some models have an LCD that shows state of charge expressed...

The DC system sounds completely self-contained, is that right? You've just got a charger and an inverter connected to a battery, the battery being maintained by the charger and the inverter sitting off and ready to move the power cable to the furnace over when needed. You don't need to ground...

Interesting, I hadn't noticed that they pulled v1.18. I have the original Conext Gateway also and installed v1.18 without any drama back when it was released. If anyone needs a copy, PM me. I am using both XANBUS busses. This unit is hardwired to ethernet and WiFi is disabled, perhaps...

Since mentioning powering a Starlink with 48V, that would be accomplished with Power over Ethernet, and presumably a DC PoE power injector. I posted a solution to powering a Starlink, or any Passive or active PoE device, safely from a 12V DC power source...

There is nothing I hate more than my Flooded Lead-Acid batteries, but I am committed to keeping the promise I made to myself that they would not be replaced until something Lithium Iron Phosphate or Sodium Ion becomes available with USA-manufactured cells. So, they remain in-place for now...

There is no problem putting the appliances at the end of extension cords. You should not consider unplugging an MC4 connector under load, this has a likelihood of causing flash arcing in the connector even at lower voltages. In the (unrecommended) absence of a PV disconnect switch, and in an...

I run with the chargers disabled normally, but enable them manually to equalize. They work fine with those limitations when left enabled. I toyed around with some settings to see if I could limit them to just keeping the batteries above 50% but below 70% off of voltage alone. Couldn't get...

Being personally unfamiliar with Vega, I read up on some specs for it. There appears to be several power levels of the DY220SL available: Every version of the DY220SL appears to be intended to be directly powered by a PV array with a voltage range between 220-370V DC. Your original post says...

Being a detached shed system, I'd be inclined to keep the battery voltage at 12V. That would give you the flexibility of implementing an assortment of 12V LED lighting for the RV market. You'll have plenty of power for exterior lights and landscaping too (also 12V). For USB charging, there are...

I'll assume this will be an out-of-pocket new installation, and probably off-grid since you mentioned batteries. There are hundreds of variables to proposing a system, but every design begins with getting answers to many questions. There isn't enough information here to help with designing a...

I like the suggestion to slide the panels on the existing rails on the Southwest and Southeast-facing sections to add 3 more. There appears to be plenty of rail up there, maybe it was a rushed job, looks horrid but works out good in this case. You can add a total of 5 more if 2 are added to...

Are you disconnected from AC1 and putting the XW into Standby using Insight?

They're struggling already with resistance, 4 years old. Each day I let them run down about 20%, the next 30% I keep around for power outage. It's eight 440Ah L16s - comedically undersized for a pair of XW Pros. It would take 80kWhr of usable storage to fully utilize the system I have now...

Natural gas prices are rising parabolically here. I have a late 90's set of Maytag Dependable Care washer and natural gas dryer. A few months back on a whim I looked at FB Marketplace to see if I could find a matching vintage electric version of the dryer and found the exact model 10 minutes...

Solar Edge optimizers are each an MPPT DC-DC converter, with communication back to the inverter, but they even work with a non-SolarEdge inverters since they function autonomously. The optimizer emulates a solar panel in the string. The number of amps that passes through each optimizer in...

Want to go over the physical changes required to convert a Split-Phase XW Pro to Single-Phase in preparation for 3-Phase mode. Internally: On upper connector, X2 moves from Neutral to L2 and a Jumper is placed across Neutral and L2. On lower connector, X3 moves from Neutral to L1. AC...

I am not sure connecting the chassis alternator and battery to the LiPO4 batteries without some sort of regulation would be adequate. Victron makes a DC-DC charge controller just for that purpose that would help. Victron is obviously not inexpensive, but it's on a completely different level of...

Good. The Rooftop Solar INSTALLATION industry, as it stands today, needs to be decimated. Generally speaking, that segment is predatory and misleading, and uses the same tactics car dealers do where they talk only about monthly payment and not interest or term. Solar Installers are in the...

Until reading this thread I never tried searching for 240V DC nominal MPPT Charge Controllers. They actually exist. Might not be able to get a manual in English, but they exist!

Up above I mentioned a "tie handle" for the two XW Pro circuits. With them now tied into a common busbar at the PDP, I can't have two un-linked double-pole breakers supplying the two pairs of 4AWG cable. Since the main panel bus bars (30+ years old) are rated to only 100 Amps, this pair of...

I read through the other posts and didn't see it mentioned, so I am going to say that this being a mobile application should have an inverter specifically intended to be installed in a vehicle. A wall-mounted inverter not the right choice here due to vibration, cooling, and form-factor...

I am running dual XW Pros with the entire house on the load side of the inverters through a transfer switch and sub-panel. That sub-panel includes a 4.5 ton central air conditioner, a 2 ton garage AC unit, and another 2.5 tons combined from 3 individual bedroom AC units. The XWs can start and...

These types of UPS/Alarm SLA batteries only have a life of about 5 years, and the clock starts ticking as soon as they're born. Regardless of sitting on a shelf, or being actively maintained at a full charge, they just do not last. In the 20+ years of maintaining all types of APC/etc...

That's an easy one actually - one of their examples. https://solar.se.com/us/en/quick-reference-design-guide/

I think it would be simpler if it were a single 240V hot and a Neutral. What we call "single-phase" is really "split-phase" or actually even 2-phase with the 120V sinewaves 180-degrees apart. Both conductors are hot, and both have 120V potential to ground and 240V between each other. The code...

I've used this resistor only one time for the initial pre-charge of the capacitor bank before coupling it to the main battery DC bus. I don't anticipate needing to use this again unless it becomes necessary to disconnect and discharge them, and then recharge again before reconnecting. Unless...
