The Delta "Surge Protectors" were the most common years ago, and not expensive -- we still have some here, still in their original packaging. The pic of the data sheet in Mike's post note that the Delta uses Silicon Oxide technology (Sand). Here is a Link that shows some comparison testing between a...

Re: My charging settings

Hi Jim, I am NOT Tim, but ... Looks like your EQ voltage is a bit low -- Trojan specs EQ at 64.8 V. You might try bumping up the Vabs a bit to see if you can get the SGs up a bit closer to targer. Usually battery manufacturers recommend EQing when the SG variation exceeds a certain number of points ...

Re: battery switches

I recently purchased a new set of batteries for my off-grid system. The old set, though 12 years old, still has strong performance.

Re: Absorb question for lead acid batteries

Mike is correct about the way to look at the Surrette Absorb time formula. This is the IUI profile, which is generally just not possible with solar-powered off-grid systems. This makes this formula (IMO) relatively useless for our solar, off-grid systems. Have always used either CC EA (ie with MX-60...

Hi Mike, YES, you are correct about the orientation of this breaker design. IMO, the breaker mounted with its handle pointed up, or down, will still try to trip.

Re: Breaker keeps tripping

It is not exactly clear what is the system voltage, but, with 58 A max observed output current, would guess that this might be a 24 V system. But, anyway, this class of circuit breaker might be considered to be junk. It is a Thermal breaker, with an unspecified AIC rating. Breakers that connect to o...

Hi whans .., Generally, circuit breakers protect cables connected to them. So there are probably circuit breakers on the genset, and on the input to Radian system. So, the cables should be sized to the smallest breaker in use, or a larger cable size. Use an NEC Ampacity table for the 75 degree C Amp...
