Re: PIP-4048MS and PIP-5048MS inverters

my batteries: https://www.wholesalesolar.com/cms/specs-3614810581.pdf Huh. I've not seen that before; phase 3 is supposed to be constant current at 5 A. A PIP-4048MS, indeed any PIP, can't do that without help from an external computer. I charge at 58V and floating at 54V Those don't sound unreason...

Re: PIP-4048MS and PIP-5048MS inverters

my 8x6V crown lead acid batteries bought 2 years ago do not hold a charge. It's easy to lose lead acid batteries prematurely. Crown seem to make a proper deep cycle battery, so it seems you could do a lot better. I could not quickly find the charge voltages for these batteries; what settings are yo...

Re: PIP-4048MS and PIP-5048MS inverters

i hear you on the 3S, I can still do 2S but the distance from the panels to the inverter is around 12M so I was thinking cable loss would drop the voltage enough that it isn't too much of an issue, would you still go 2S?

What is the PV voltage when this is happening?

Also what is the battery voltage doing? Perhaps the battery is full, or has gone high internal resistance?

Re: PIP-4048MS and PIP-5048MS inverters

The installer set the battery type to flooded instead of AGM and I'm sure my batteries are poked! The maximum charge voltage for battery type FLD is effectively 58.4 V; for AGM battery type, it's 56.4 V. So these correspond to 14.6 V per 12 V module (flooded), and 14.1 V per 12 V module (AGM).

@coulomb So for VMII with DWPH fans, the PWM "030" speed is 3240~3300 rpm keeps varying in that range, according to laser tachometer. Ah. I had assumed that a 3-wire fan doesn't listen to the PWM signal at all. Hell, fan A doesn't even have a wire on the PWM signal (pin 4). So you're saying that at...

Re: PIP-4048MS and PIP-5048MS inverters

Even with 1.5kw load, fans were slow. Yes. For the load portion of the fan speed, the speed is simply scaled to the load, proportioned to maximum load, with 30% minimum. So the fans don't start speeding due to load until 30% x 5000 = 1500 VA. With more than 2kw solar, the fans were fast ... Yes. Fo...

When Fan B right hand one switches On , Fan A reduces it speed. If they are really spinning at pwm 30 speed how on earth w...
