Thanks! Great feedback. Yeah. I'm torn about spending the $$$ (even at Cyber Monday discounts) to have the convenience of compact grab-and-go power solution I can just throw in the camper/RV/truck, rather than DIY one. I own the Growatt Infinity 1300, which has better solar input (1200W @...

Yeah. I figured. Wishful thinking. Oh well. Thanks.

I've searched for a definitive answer, but am still not clear on whether or not this particular Delta 2 power station can be connected to another identical Delta 2 using the battery expansion port via the XT150 cable. https://www.amazon.com/gp/product/B0B9XB57XM Can it be done? What about...

No replies yet is see. How are the BougeRV CIGS panels working for you? I'm ready to pull the trigger and buy some now that the prices have come down a bit. But would like to know your experience first.

The Tech Specs

I just purchased this new Growatt Infinity 1300 SolGen/Power station. Problem is that Growatt doesn't provide an add-on external battery option. ? So, I'm going to do a DIY add-on battery by connecting an external LFP battery bank to the Growatt's solar PV input. Of course, the Growatt won't...

Well, since I don't think you got a direct answer, here I go, as I just developed the following rule of thumb ballpark estimate for my location. I based my calculations on how much energy is needed to recharge a standard 100Ah 12.8vdc (1280Wh) battery, readily sold today. I consider that a...

Works fine in winter months (15% lower irradiance) at my latitude. My main power usage is AC, which I don't need in the cooler months anyway. You have to go on the assumptions provided. MPPTs claim even higher efficiencies than 95% I'm using. I'm not designing a specific system per se, not...

I'm operating in an area with an average 5.5 peak solar hours per day (panels tilted to the area's latitude facing 180° due south). So, if I assume 95% charging efficiency of the MPPT solar charge controller, then I get the following for numbers of Watts/Panels I need to fully charge a single...

I'm in the market for a small/medium sized portable power station solution for off RV'in and offroading. The Vigorpool Captain 1200 checks off a lot of boxes for me -- especially being able to parallel two together for 2400W of power and 2560Wh of energy (paired), for higher loads and more...

Has anyone attempted and succeeded at paralleling two identical model Pure Sine Wave inverters to double the power output? This is a common feature of some of the larger the All-in-One inverters, and even a couple of smaller power stations (i.e. Vigorpool Captain 1200), but I'd like to be able...

Yeah, like the EG4's I already mentioned? But I'm not looking for an AIO inverter with high PV input voltage. I want a separate SCC than can handle, say, 150vdc to perhaps as much as 500vdc PV input. I prefer to build my system with individual components for serviceability and redundancy rather...

I see your point. Yes. The rated current of a SCC is the DC output, not the PV input. Do I understand your point correctly? So, to clarify, higher output current on a SCC does indeed equate to more charging power, regardless of the SCC's max input voltage (Vmax), at a given output voltage...

Uh. $$$$$$$$$$$$$$$$$$$$$$$$$

Who said anything above any particular voltage... especially 600V!!??? Not I. I think 500V is way more than I'd like to panel in series. But having enough headroom for some of the high Voc's on some PV's is that margin of error I like to design with.

Inspired by the latest EG4 AIO units with up to 500vdc PV input, I'd like find the best options (excluding Victron) that accept higher PV input voltages. Any recommendations? In the past, I'd search for high *current* MPPT SCC's, thinking I'd get most charging power. However, I failed to really...

I've been looking at Variable Speed pool pumps for a 20,000 Gal pool on solar. I'd probably have a dedicated solar setup just for the pump, separate from the house system. You say you've installed quite a few VS pumps? What could you recommend that ramps up it's starting current? The current...

A follow up question... In this temporary emergency connection, should the Growatt's ground be connected to the panel's earth ground bar (since the panel and it's circuits are is earth grounded) and the neutral to the panel's neutral bar? I don't thing that earth and ground should be bonded...

2000W / 12vdc PSW -- $179 on Amazon For $179 this looks like a no brainer for a tiny RV build, where my largest peak continuous load is likely 1200W for not more than a few minutes. Most of the time I'll be under 500W. Does anyone have experience with this brand, or this particular inverter...

Did you purchase this inverter? If so how did it work out for you? I looking at the 2000W @ 12vdc model. For $179 it's almost a no brainer.

https://www.amazon.com/dp/B0BF94WPW3 What's the general opinion here on using this car jump starter in parallel with a 12vdc bank of LiFePo batteries, (100A or 200A BMS current rating), for inverter loads that may temporarily exceed the BMS max current, say starting AC's, pump motors, etc?

The beaches and coastlines of the world, just to keep things simple.

Okay. We have a starting point. That Lixada 10W panel specs: 10Watts, 10.2in*5.5in*2mm @3.6oz ==>> .4s.f. area, 25.7W/s.f., 2.8wW/oz. It will definitely fit my 12"x16" pack. Any other suggestions?

I'd like input on the best type of ultralight PV panel suitable for backpack travel. Weight is the number one factor, as in watts/ounces. I have a very small backpack that could accommodate a panel size of up to 12" x 16" . Anyone found something that works for them on the road and on the...

I did a little more checking and found this similar unit. I like that it has the split core current sensor so i don't have to disconnect a wire to feed through it. https://www.amazon.com/Current-Amperage-Voltmeter-Multimeter-Transformer/dp/B07JB9B2QL

There we go. This is getting close. Looks like I'd have to wire in a plug to the green voltage input terminals, with the hot side passing through the current transformer coil, if I'm understanding the wiring diagram. Too bad the case is so big to accommodate the capacitors on the board. It's...

Thanks for the re Thanks for the suggestions. I recall looking at that bluetooh unit some time ago. But they must I'm not in the market for another spyware device -- the unit/app requires an account which I'm certain is sending info back to the deep state mothership. I'd prefer a standalone...

Many people use one of the power savings meters, e.g. Kill-a-Watt. I have a few, including a very old Kill-A-Watt P3. However, I looking for something much smaller, lighter and pocket-sized, that would travel well in my backpack. There are so many very small DC power meters available. But does...

WOW. Great suggestions guys. Thank you. Okay, to clarify a bit about my loads and needs, since some of you asked... * To reiterate, this is only for TEMPORARY emergency use, such as an extended outage due to storms and such; not a permanent wired solution * max input is single-phase 120vac @...

I'm only asking for suggestions for wiring in my Growatt SPF 3000TL LVM via an 30' extension cord/pigail into the house electrical panel only for critial loads during extended power outages (think hurricanes). Here's the house electrical panel, with mains coming into the two 125A breakers...

Hey guys. What's the latest/greatest recommendations for small Pure Sine Wave (PSW) inverters, both 12/24vdc, 1000w and 2000w that are readily available on Amazon? I've been playing with this Bestek 1000w PSW inverter for a while now. It does a great job for most of the loads I throw at it...

Why not a hybrid approach? Purchase the cheap, pre-made, Amazon-available Off the Shelf (OTS) batteries and take them apart ala @Will Prowse style? You can then mess with the innards of the cells, BMS, connections, temperature sensors, etc to you liking. Augment the pre-made components with...

Great. Thanks. I found a demo video on YouTube. Looks like it still cycles a relay to maintain a temp, just with more granularity. I assume it's maintaining a preset temp? Or is it maintaining a preset power level? Perhaps you can set either?
