Re: [RE-wrenches] Conext SW4048 not charging from generator

Dave, You're not far from me, so I know that the temperature at the site has been well below freezing at night. After running a series of cheap generators here for many years I can tell you that there's likely water built up at the bottom of the fuel tank.

Re: [RE-wrenches] Conext SW4048 not charging from generator

The log in non volatile memory (if excessive) would show under events (current and historical) in Gateway for the CSW40408. It might also be in SCP for the device by scrolling down to view device info, enter, faults and warnings. There will be dates and fault and warning numbers. If this all

Re: [RE-wrenches] Conext SW4048 not charging from generator

Try having them decreasing the Max Charge Rate to 50% and monitoring the AC output, specifically looking for spikes and dips in voltage and frequency via the SCP. Although you can open AC input parameters to allow for dirtier power to be qualified, I would definitely suggest against this. Sounds

Re: [RE-wrenches] Conext SW4048 not charging from generator

Definitely the generator.  Harbor Freight?  4 kW into a 4 kW charger?  What's the altitude?   I believe that 4 kW generator is actually only 3.5 kW continuous rated.   By the time you derate for altitude, and then account for the generator not being built to be a prime power unit, its probably

Re: [RE-wrenches] Conext SW4048 not charging from generator

>From what I understand, they have had the system for a little over a year, and have not done any maintenance on the generator. I was also more suspicious of the generator, and was going to try turning down the charging amps to see if the generator will work better not being so loaded. Dave, do

Re: [RE-wrenches] Conext SW4048 not charging from generator

HI Dave, Have them turn down the AC input and see if that fixes it. Sounds like a classic generator issue. As to why? When did they last change the oil, air filter, fuel filter, spark plug, adjust the valve or some electronic issue with the generator. jay peltz power > On Dec 15, 2020, at

Try lowering the max charge amps incrementally. Dave Tedeyan December 15, 2020 at 10:14 AM Hi All, I am going to service a system where the homeowner is telling me that their Conext SW4048 had been working fine for 14 months, and then all of a sudden recently

Re: [RE-wrenches] Conext SW4048 not charging from generator

Dave, I would first suspect the generator, not the inverter. Check its output voltage and Hz under load. If it's overloading, either (or both) voltage and frequency will drop below the acceptable range and the inverter will unlatch its input relays, wait for a bit, relatch and ramp up input

Re: [RE-wrenches] Conext SW4048 not charging from generator

No Sir! Never use a cheap genset on any inverter/charger. It is the best way to ruin the input relays. The alternative is to have a spare DC charger for use after the inverter/charger has been damaged. Schneider also logs this for warranty. I would assume that Outback Radian does also? Dave

[RE-wrenches] Conext SW4048 not charging from generator

Hi All, I am going to service a system where the homeowner is telling me that their Conext SW4048 had been working fine for 14 months, and then all of a sudden recently stopped being able to charge the batteries from the generator. It is an off grid system. The inverter would start charging the
