    Best gas generator for a backup battery charging?

    It wasn’t quite bad enough at first; when I finally realized that it wasn’t working properly it was too late to return

    Best gas generator for a backup battery charging?

    I have been less than happy with my Honda EU1000i - like many on here I went with the Honda based on their reputation for reliability and quiet operation. However, the unit I bought must have been a lemon as I have not been able to get good, stable operation at full power (although no...

    looking to buy used solar panels, need thoughts.

    Any other recommendations from the forum for sources of used panels, preferably on the East coast? I know Santan is opening also in Savannah, I'm also looking at panels from Signature Solar.

    looking to buy used solar panels, need thoughts.

    I bought 10 of the Santan (Trina) panels last May and they all worked just fine, yielding close to rated power on the best days. Typical in September-October at mid day seems to be around 1700W for 2250W nominal (my array is 3x3). Shipping was expensive though and when I looked recently is...

    Ordered 8 EVE "new" 280Ah cells from Shenzhen Luyuan

    I didn't use a battery tester to generate the graphs, just used the JBD BMS to read out cell voltages and then put the data in Excel. Capacity on the first pack came out just as expected, roughly 286Ah as measured by a shunt during discharge testing down to the first cell reaching 2.9V. I...

    Ordered 8 EVE "new" 280Ah cells from Shenzhen Luyuan

    Very happy with the matching of cells from Shenzhen Luyuan. I assembled a first pack of 4 cells, added a BMS and started top balancing with a bench supply to charge the pack, using the BMS to cut off when the first cell reached 3.65V. Initial balance as received was very good, as shown by the...

    Ordered 8 EVE "new" 280Ah cells from Shenzhen Luyuan

    Well, it took a very long time, but I finally received my 8 "new" 280 Ah EVE cells from Amy at Shenzhen Luyuan. All cells arrived well packed and in excellent mechanical shape, I will now start top balancing and putting together a battery for capacity testing. I am very happy with the company...

    Panel power production/tracking

    I just bought the Cerbo GX - judging from the demo program (I don't yet have the required VE.Direct cables) the data displayed is pretty basic. Nowhere near the minute by minute data graph I can see using the Bluetooth connection direct to the Victron device. Am I missing something? All I want...

    Schneider SW4024 initial review/use with Victron MPPT

    Maybe my expectations for the online software were too high. It does an adequate job of reporting daily totals for load and battery consumption, but is not useful for showing me instantaneous details. I wonder if the CerboGX (when the connection works) does a better job of minute by minute...

    32 280Ah Eve "grade a" from Shenzhen Luyuan (Amy Wan)

    Are you concerned at all about long term corrosion between the copper bus bars and aluminum terminals? I'm also using copper but eventually want to get around to tinning the leads. I'm curious about what others are doing.

    Schneider SW4024 initial review/use with Victron MPPT

    After a couple weeks of operation I thought I would share a few more notes on the SW4024. First, the inverter has, so far as I can tell, functioned flawlessly. It starts all the loads I want it to, and for medium to large loads has good efficiency, >90%. I chose this as it seemed to be by...

    Schneider SW4024 initial review/use with Victron MPPT

    Thanks - glad to hear that you've been satisfied with long term operation. I assumed I would need to fiddle with the charging parameters to make it work - most likely I will just leave the charger disconnected unless I need it. Any quirks of operation or failures that you've noticed?

    Schneider SW4024 initial review/use with Victron MPPT

    I forgot to mention - does anyone have experience using the Victron MPPT Smart Solar series with the Schneider inverter? I don't really expect that I'll be able to connect the Xanbus (Schneider proprietary interface) to the Victron, just wondering about settings that will allow the built in...

    Schneider SW4024 initial review/use with Victron MPPT

    I haven't seen much out there on the Schneider SW4024 recently so I thought I would share my initial impressions after getting it installed. My primary reason (as usual) for a split phase inverter was to be able to start my well pump. This inverter is rated at 3400W continuous but 7000W for a...

    Results of testing new panels from Santan Solar

    Yes, I measured the panel temperature at about 125F - this should drop the efficiency by around 10-15% from 25C. Panels I bought weren’t the snail trail ones by the way, I bought them just before the price increase, they are the standard Trina silver frame panels. The only downside to these...

    Results of testing new panels from Santan Solar

    I had a good experience with SanTan solar - I was a bit hesitant to try used panels but the price is too good to pass up. I ordered 10 of the 250W silver frame (Trina) panels at $50 each plus about $250 total shipping with delivery to the local Central freight terminal. The packing was good...

    Maybe something like this: https://simondstore.com/ceramic-fiber-products/ceramic-fiber-board/simvac-ceramic-fiber-board-2300-f.html After reading about the OP experience I'm going back to review what I should do better for fire supression

    Ordered 8 EVE "new" 280Ah cells from Shenzhen Luyuan

    So far very happy with the response from Amy at Shenzhen Luyuan - payment received 7/9, on 7/17 Amy posted pictures of the wrapped boxes and a link to the measured data (shown below) - I'm not exactly sure at one point the voltages are measured in their test routine, presumably after full...

    Last fire.. :-(

    Thanks for sharing @fhorst - perhaps we can learn from your experience. It is a good (and very visual) reminder that the energy stored in LFP batteries can be extremely hazardous; we all need to take appropriate precautions.

    Ordered 8 EVE "new" 280Ah cells from Shenzhen Luyuan

    Thanks - I do know it will take a long time, hopefully less than 3 months though. What’s causing new delays?

    They will come with welded studs (M6 I assume)

    Ordered 8 EVE "new" 280Ah cells from Shenzhen Luyuan

    Also placed an order for 8 new 280Ah EVE cells from Shenzhen Luyuan; order process was pretty simple, looking forward to delivery and testing. I expect the shipment to take about 2 months, after which I will update the forum with test results.
