The beeping may be a low voltage alarm. Check to be sure the batteries are charged and or the cables are not corroded. The hwh system pulls a lot of power and seem to always dim my lights a bit when operating.

Dennis,

Make sure you're plugged into shore power or run the generator to assure you're getting the maximum voltage across the house batteries as possible (charging). If you have one or more batteries with shorted cells you're going to be fighting an uphill battle.

Yes, bad house batteries can definitely affect the HWH system. Low voltage on the pump motor is NOT good let alone the various solenoids & relays involved.

Check all your grounds. These things are notorious for going crazy because of a bad ground.

I found a loose ground at the control box when my HWH became erratic.

How old are your batteries, Dennis? Do you have a meter to check the banks?

I think you might have found your answer. If you decide on the AGM batteries, make sure you make the change from "flooded" to AGM within the Silverleaf. Also be careful when you change out the batteries. The outfit that changed mine fried the Xantrex and had to replace it.

Dennis,

A bad battery (shorted cells) acts like a "shunt" and drains the other batteries as well as the charging source. The available voltage and amps getting to the HWH system (relatively far away from the batteries) would not be sufficient. I would replace the batteries and then re-evaluate your system.

My Xantrex SCP displays the amount of amps currently required to charge the batteries. It also goes through stages of "Bulk", "Absorption", and "Float". If yours display the amps and that amount is greater than 5 - amps or never reaches "Float" stage then it's probably running at a constant full load indicating a battery problem.

FWIW ... I have Interstate wet cells that are 5 - years old and still going strong. I use the Pro Fill watering system regularly to manually keep them full of water which is a very easy task (very little cleaning!). I use a "hydrometer" to test individual cells and a load tester to check chassis batteries. Sam's Club has Energizer GC2 golf cart batteries (232 AH) for $112. The Interstates cost about $140. I'll replace mine with Interstates (personal preference).

If I remember correctly, the HWH operates off the Chassis batteries, not the house. Can you lock and unlock the front door with the keypad? If not, or if it's quit working, it's because the chassis batteries are under 11 volts. Probably not enough to operate the HWH either. You can check the status of your Xantrex with the Silverleaf. Our Apex's don't have an SCP.

Perhaps WRV changed the battery source for HWH in later model years but the pump and associated solenoids in my '03 definitely operate from the house batteries. The cutoff switch in the stairwell turns the HWH off & on. I believe the control panel and electronic "box" inside the console works off of the chassis batteries (ignition must be on "acc" or "ignition").

One way or the other, the batteries are suspect based upon the available information.
