Charging ?

What is the amp capability of your charger sir? I read your article thrice BTW. Yout=rs sounds appropriate for solar but it sounds like it needs slightly more than an arm-twist to compensate for adding a battery. The most important difference is this.

You can put the power supply and timer together for eighty dollars. It can actively envelope 100 to 240 AH range it's how much you have to twist that dial. Your system sounds much more appropriate for solar.

I need to repeat this again THIS IS NOT A CONVERTER IT IS A CHEAP EFFECTIVE BATTERY CHARGER THAT ELIMSTES EARLY BATTERY DEATH. Eliminate is a powerful word.

Click off the breaker for the converter
Go to a side bay
Grab the Meanwell plug it in
Connect clamps to battery posts
Twist dial

When the Meanwell clicks off the generator will surge.
Shut the generator down.

Your idea has merit but it's not for this job.

Remember, when a converter returns home and goes on a pedestal it has the luxury of 24/7 error correction. Then a simple twist of a dial when the Meanwell has engaged once again on shore power can compensate and correct for the chemical incompatibility between your algorithm and reality.

This is not celestial mechanics or counting quarks. It is a broad span voltage correction. Inexpensive and easy to understand.

Your idea is intriguing but must be made adjustable. Electricity and chemistry amalgamation is not the easiest subject.

The Meanwell and Timer is awesome

I don't know what you mean by 'this job'.

The question is whether my system is automatic, not whether it is for 'this job'.

It is based on my collecting logs for review and setting up an automated system that would saturate-charge my battery bank. I believe I have met that goal.

Since you have read the topic three times, I will attempt to make a clearer explanation.

The details of the charging amps and size of the battery bank are irrelevant. However, the bank is 620Ahs AGM, 400W solar, 75A PFC charger, and 1600W running inverter genny. At 10k feet, the genny gives 1000W.

Each day there is a timed charge with the purpose of reducing the charging Amps to the 0.5% goal. That definition is straight out of the Lifeline manual, pp 5.4 - Charging.

This is done by the solar controller when it starts a new day. It is set to compare overnight low Volts(onlv) using two trigger Voltage values.

If the onlv is above 12.6 then the Abs timer is set to 1hr followed by Float.

If the onlv is above 12.4 then the Abs timer is set to 2hrs followed by Float.

Otherwise(below 12.4) then Float is cancelled and Abs is until dark.

These tests are features built into the solar controller.

So you see, an onlv falling low Volts will be caught and corrected in the same way you might add time to your twist timer.

Simultaneously, I have a small computer keeping a log by fetching key statistics from the controller each minute. I can examine this log and produce graphs as you have seen in the other topic. I use this computer to talk to the controller. That is how the Voltage and time parameters are set up in the controller.

I believe this makes the system adjustable in real-time. I could use the computer to examine ongoing operation and send ad-hoc commands to the controller. After about a year and a half of operation I have seen no need for this.

I have used all available roof space for solar panels and I do have a 75A PFC inverter-charger which is all my genny can handle. The 75A charger allows the Amps to be adjusted.

I don't have any objection with a Meanwell power supply. I do have a question. Which Amp one would be useful at 1000W input considering PFC? How would that outperform my PFC 75A adjustable charger?
