Re: [RE-wrenches] small inverters

Jay, The Exeltechs can be routinely ordered with the Low Idle option, which I think brings the idle draw down to 10W. In some small applications, a remote on/off switch allows the user to manually (or otherwise with additional external control, I suppose) turn the unit

Re: [RE-wrenches] float switch for grundfos submersible

Bill, I have always used the CU200 ("Sorry, sir, that's what it costs to give you what you want...") when a float switch is called for (which is nine times out of ten) so I haven't done this, but: The only alternative to their proprietary product would be a means to

Re: [RE-wrenches] Battery charging problems

That doesn't make sense, the inverter's charger determines the max charge rate and the max draw from the generator. The 8.5 kW Kohler should have no problem running the 4.4 kW Magnum. What is the altitude? Is it wired for 240 vac ? If the generator is running at 120 vac, then you are only

Re: [RE-wrenches] Battery charging problems

Hi Chris, The problem summary is a bit light on details to be too specific. What, precisely, does a generator running "rough" mean? Overheating? Smoking? Breaker tripping? THE MS4448 has about 3 kW charging capability (63A @ 50 VDC). So the 8.5 kW Kohler should be able to handle that

Re: [RE-wrenches] Does a Neutral Count as a CCC

William, I agree about the subpanel in the house situation. The customer is a bit eccentric, and I have tried to bring him around. And I have explained to him that his approach will be more expensive. He doesn’t care. In the end, there is no safety risk. So I’ll plan for 4 branch circuits

[RE-wrenches] Battery charging problems

Dear people: I have an off-grid customer who has, in his system, a Magnum MS4448 and 16 of the Rolls S550 batteries, a Kohler generator (and Trimetric meter and other components). He upgraded his batteries this past March, and since he's installed his new batteries, the generator is running

Re: [RE-wrenches] Does a Neutral Count as a CCC

Peter: I think it is a mistake to not locate a sub-panel in the house. Running branch circuits 45 feet to a separate building is not efficient or practical. Voltage drop: 1% VD is a choice, not a requirement. Code requires 3% on feeders and 5% cumulative on AC branch circuits. I like to

Re: [RE-wrenches] Does a Netral COunt as a CCC

Also look at the notes to the tables in Chapter 9. For conduit fill, all wires are counted. 310.15 covers ampacity derating for more than 3 current carrying conductors in the raceway. The key is "current carrying conductors". The neutral definitely carries current. You don't have to count

[RE-wrenches] Does a Netral COunt as a CCC

I am working with a customer who is doing a complete remodel and addition to his house: stripped to the open studs and floor joists, and rafters. Not a wire in the house. We have designed a 14.4 kWp PV system with 16 kW of storage for backup and load shifting. The main panel, inverters, critical
