Maybe. Check out 5.2.1 here and see if your converter can do that or is doing that. Assumes you have a meter and can tell what's going on. Check your batts with an hydrometer to confirm (scroll down for how to do that too)

It is a Trojan guide, but applies to all pretty much.

My 8900 has a 3 stage charger.

The 8900 Series has revolutionized RV power centers with its lighter weight, decorative doors, and superior features. 8900 Series models provide a clean, constant 13.6 VDC output for reliable operation of electronics and appliances.

Automatic 3-Stage charging maintains the life of your batteries with output voltages of 13.2 VDC (Sleep) mode, 13.6 VDC nominal charge, and 14.4 VDC (Boost) charge. 8900 Series also maintain peace and quiet, as the cooling fan runs only when needed. When the fan is running, it is so quiet it goes unnoticed.

Looking at this Renogy 2000w PSW inverter with remote monitor. Any feed back would be appreciated.

The only thing is that there is a 2000w New Edition that is out of stock and not available. Really don't know what the difference would be.

i dont have that but use othe Renogy products. all have been good, they have always answered the phones when i had questions and called during business hours.

looks like the major difference is the new edition suports there bluetooth modual

WFCO is poor at best and is generally considered a fixed 13.6 volt power supply and not the 3-stage charging listed as a feature. However with 500w solar the WFCO is fine as a standby system.

The WFCO blurb is one thing, but do you know if yours does that? Many don't due to wiring issues etc. Do you see the 14.6 ever? (Assuming you have a meter so you can tell) Are your batteries ok (by hydrometer!) having been under that converter's care?

30 amps (assumes 8930, not a "30a" system (ie 120v 30a) is very low for a bigger battery bank, so your gen time will be very long, waste of gen time. Your gen can take up to a 60 amp charger, so for the winter time , no solar, you could go to a higher amp converter.

I prefer the PowerMax LK models with their adjustable voltage choice that most converters don't have. There are other choices. Anyway, it is not long now till the warm half of the year when solar works best, so no hurry if the WFCO is doing 14.6 and the batts are ok by SG. Next Fall with the four 6s for sure though IMO.

My battery monitor is not that sophisticated. When the lights don't come on it will tell you the batteries are dead.

I am in the market for a good battery monitor. Not sure what information the solar controller is going to provide but I would like to know things like amp/watts coming and going current battery status power level.

1L243,

Victron makes two excellent battery monitors. They are relatively inexpensive. They do require the use of a shunt.

What stops me from going to 48 volts is the inverter, and charge controller.

Unless you can get a good price on your current equipment, I understand completely !

Sigh. Other said it before. When you buy a kit, you are not getting the best bang for the buck !
