The crimper itself has worked great. I like it. I think the problem may be that the lugs here are thinner than they should be, which leaves the finished crimp looser than it was designed to be. It's hard to get good quality products here. It is also possible that the cable itself is not...

Using a bought-in-Thailand hydraulic crimper (around 700 baht), we quickly learned that the cable sizes did not match the crimp dies. The nearest size die to the cable diameter left the lug loose on the cable--loose enough to be able to slide back and forth on it about a millimeter. Of course...

If your welder requires 240-volt, 20-amp input to operate, that's about 5 kw of power (volts x amps = watts). You should be looking for a 5kw or better inverter. I think the welder might operate at lower amperages as well if it is not using its highest settings, e.g. if it is, say, a 160-amp...

Class T fuses are not cheap. And they are not instant, either. When I was doing my research on this (on account of the high price tag for Class T), I discovered that whereas I had thought they were almost instant, they also have a delay before blowing. Another fuse, at a much cheaper price...

Yes. I'm not sure exactly where or how the battery is produced, but it looks nice, both inside and out. I torqued the connections inside once it arrived and found only one of them loose. The cells are 280AH CALB cells, rated for 9000 cycles. The BMS is a JK 150-amp version. It has four RJ45...

Well, I would like to know how the inverter will communicate with the battery's BMS via WIFI. Because the manufacturer finally got back to me yesterday saying that the RS485 port was not designed to communicate with a battery, but rather to be used for WIFI. The problem with this explanation...

I'm still trying to reconcile this statement with your tagline: "I don't want to know why you can't. I want to know how you can!" I have never heard of LiFePO4 batteries becoming bombs. Do they? I used to have FLA batteries in my bedroom--never had any major troubles, but I did notice some...

Thanks for chiming in. I'd sure appreciate some documentation to back this up, if you or anyone else has the details. And would 5-volts on an RS485 port be expected to cause damage?

Yes, seriously. If you really wish to look into this, you may download an English translation of the Thai "Commission of Computer Related Offences Act" from the United Nations server HERE. The law specifically applies to internet activities, including "defamation" (which still applies here...

Well, if you can believe it, I don't have the option to buy any of those in Thailand. Not one. Victron is completely unavailable here, and I've looked for the others, too, with no success so far. Now, if you can point me to a domestic source within Thailand, and/or one that is accessible via...

I'm not convinced that is the answer. The Sigineer seems quite different from the LVTOPSUN model that I had. The LVTOPSUN is a toroidal, LF inverter, with an advertised momentary peak output of 3x its rating, whereas that Sigineer makes no such claims, resting on a 2x peak for five seconds...

Well....supposedly, LVTOPSUN doesn't either. Just the same, I have one.

Well, take this with a grain of salt. I'm in Thailand, and good information here is scarce. What's more, it is against the law here to post negative information online about anyone or any company, punishable by jail times, which exacerbates the information gap. But here is the information I...

I believe this may be accurate for Deye, Sunsynk, and Sol-Ark. However, with LVTOPSUN, the firmware is definitely not the same--at least, the GUI/interface is rather different. The LVTOPSUN, for example, has no option of setting battery-usage times, as I understand the Deye to have, and the...

The manual that came with it gives the pinouts for both RS485 and BMS. However, the 3KW model has only one port, which is labeled "RS485" on the unit itself. The 48-volt version of the 3KW LVTOPSUN seems uncommon. I don't find any in stock at the moment, and the manufacturer does not even...
