11 Fixed Voltage Settings For a 130 Ampere Charger

This is meant to be fun and not a challenge :) And the issue is not theoretical... Here we have a mean mean Meanwell RSP charger that has a max potential of 130 amperes. And the user cannot or d...

  • Of course generators require more fuel the greater the load
  • And they wear out slightly faster when loaded
  • THIMK! What is one of the biggest assets of an inverter generator?
  • They slow to meet the load demand
  • Unloaded the Kubota uses about .65 gallon per hour. Two dollars and change
  • Pistons go up and down oil gets dirtier as the engine runs. Eleven quarts of Delo 400 and 2 oil filters are not cheap
  • Including turbo and fuel system an "in frame" costs $5,500. My pickup can only haul four drums of diesel. Maybe 208 gallons max. The nearest gasolinera is about a 38 mile round trip.
  • Fuel, runtime, total storage, how does all this fit into a serious outage of 10 days?
  • Idon't even want to think about the thirty thousand dollars to replace the batteries
  • They are on their 22nd year. Mind you they are NOT off grid merely there for frequent and not infrequent prolonged outages. When power is out and the weather is miserable the generator may run ten hours a day. 24/7 the batteries have 1 1,300 watt refrigeration burden to bear plus a 5K A/C unit that will be on 24 hours a day. A 100 Mhz 4 trace storage Tektronix oscilloscope and 6.5 digit bench meter do not say "oh sugar" when subjected to condensing humidity
  • So, I am subjected to an amplification of generator battery charging run time. And it is all serious money at best and in my case critical
  • I have measured, crunched numbers, re-measured and gone up one side and down the other
  • Saturated voltage charging just beats the snot out of any other protocol. Especially when done with AGM batteries
  • My pair of Lifelines came to the same agreement. When I find a used 8.5 HP (hopefully) Honda engine I am going to fit an LHA load handler 160 amp alternator belt driven to handle the Lifelines
  • I am still suspicious about Trojan's 14.8 volts unless they are a carbon AGM
