I would also look at if the battery is listed for residential and if homeowners insurance would accept them? UL 1973 and UL 9540 are typical requirements for the battery as a whole, and not just the cells in a battery. You really want the insurance to be there in a claim. At the minimum,

The old gray box XW's never really were designed for AC coupling. It could be made to work with a xantrex grid inverter but most were told to upgrade to the white box XW+ and XWpro. I doubt anyone would notice the XW+ or pro when it shifts a couple hz to protect the battery after it is

Hello Fellow wrenchers. Has anyone purchased and used any batteries from Electric Car Parts out of Utah. They have a 48 volt, 5, 7.5 and 10 KW Lipo battery made by Energetech ( China ) . I have a customer that would like to use the product ( low cost ) but it is tough getting any actual info from

Friends, About seven years back I connected a dozen M215 Enphase inverters to our battery backup system at home (Schneider XW4024 with 370AH battery bank). The result was something that I would never want to duplicate for a customer owing mainly to the flickering of lights during the daytime when

Allan, I have seen batteries that have been in a warehouse environment for up to 5 or more years without issue as long as they are boosted regularly. I know the distributor you are dealing with and they are good, "most of the time" in taking care of them while they have them in stock. To be

Hi Ray Depends on which rolls battery L-16’s The EX version is 3400 cycles to 50%, and 2100 cycles to 80% the more standard version is around 1800 cycles to 50% and 1000 cycles to 80%. And the Ah specs listed on the rolls site uses the 20 hr rate. Jay Peltz power. > On Jun 11, 2020,

To allans question as to if it’s a good idea to get these old batteries. If you need them you need them. I’d ask for 25% off and that the warranty would start from delivered date. Not knowing which battery model His customer is specifying , but I had a client who left his new rolls for a

As far as 2v L16s go, I've not seen good things with the Trojan L16 2 v cells.  The Rolls version looks like it is one cell though, not 3 cells paralleled internally like the infamous Trojan.  The voltages sound a bit low, can they give you SG readings? How come they haven't put those on a

Wrenches, Allan You could wait but you will not know what you get untill it arrives, I would take what you got, they need a good charge anyway and after you may find it difficult to pick out the oldest one just from voltage. Jerry On Wed, Jun 10, 2020, 11:05 PM Sindelar Solar wrote: > Wrenches,

Im sure that Steve H. will have the “official” word on this but…. I find these cells quite robust and I would suggest that your “supplier” ck the SPG then charge them, & recheck prior to shipping. These are my go to cells if they want more that the 6CPS 25-27 plate 5000 series capacity. Have I

Wrenches, Here's one I haven't encountered before, and I'm interested in the range of opinions I may receive. My battery supplier screwed up, and they admit it. On April 27 I ordered a 24V set of 2V Surrette L16 FLAs for a long time client; note that these were the client's choice after his
