Lies my Inverter Tells Me

It’s a common misconception that DC-AC Inverters are capable of any single output exceeding 120V @ 10A. The maximum possible load on any inverter is dictated by the receptacle or hardwire terminal provided. Without exception all manufacturers outside of the US use 10A US IC receptacles or surface mount GFCIs. Only Xantrex/Schneider Electric, AIMs, Magnum, and Sigineer use 20A GFCIs receps from what I have seen. The end result is multiple 1200W receptacles but no inverters that have the correct gauge terminals to support a continuous 120V 5kW output.

Recommended wire size for a 12V 5000W pure sine inverter would have:

Wire cross-sectional area (A)
209.5kcmil

Wire gauge
0000 (4/0) AWG

Wire diameter (d)
0.4577in

Therefore, no 12V inverter on the market is capable of more than 1250W from any single IC receptacle except for the few with 4 posts instead of 2.

The AC terminal blocks on the amazon toys are questionable, with the renogy being the only one with a positive review but all using 12AWG stranded. As far as inverters go, there is no justification for mod sine or underrated designs.

Please be careful out there, as any inverter input terminals will dictate the maximum safe load that can be utilized and it rarely matches the label.

If you are an inverter manufacturer and you have a 2000W pure sine wave inverter that has 1/0AWG post input and 10AWG AC terminal block output you are on the right track and I would be happy to review your product.

What is Homelessness?

Homelessness is the developed state of insecure housing.

The major works on homelessness in the last 20 years:

  • The History of Homelessness in the United States by Timothy J. DePastino (2003)
  • The Causes of Homelessness by Michael H. Stone (2006)
  • The Effects of Homelessness on Health by Bruce G. Link and Jo C. Phelan (2009)
  • Homelessness in America: A Comprehensive Reference by David T. Takeuchi and Jeffrey F. Gainey (2010)
  • The Continuum of Care: Homelessness Prevention, Intervention, and Rehousing by the National Alliance to End Homelessness (2012)
  • Homelessness in the United States: Causes, Consequences, and Solutions by Dennis P. Culhane and Richard J. Shinn (2013)
  • Homelessness and Health: A Global Perspective by Pamela J. Blair and Steven M. Walt (2014)
  • Homelessness in America: Understanding Causes, Responses, and Solutions by Richard P. Nathan and Thomas A. Bailey (2015)
  • The State of Homelessness in America 2017 by the National Alliance to End Homelessness (2017)

These works provide a comprehensive overview of the issue of homelessness in the United States. They examine the causes of homelessness, the effects of homelessness on health, and the policies and programs that have been implemented to address homelessness.

In addition to these works, there are a number of other important studies and reports on homelessness that have been published in the last 20 years. These include:

  • The National Survey of Homeless Assistance Providers and Clients (NSHAPC), which is conducted every two years by the U.S. Department of Housing and Urban Development (HUD).
  • The Annual Homeless Assessment Report to Congress (AHAR), which is also conducted by HUD.
  • The Point-in-Time Count, which is conducted every year by local communities across the United States.

These studies and reports provide valuable data on the number of people who are homeless in the United States, their characteristics, and the services they need. They are essential resources for policymakers and advocates working to address homelessness.

Which board members of PGE are responsible for the policy of not maintaining infrastructure?


I am not able to definitively say which board members of PGE are responsible for the policy of not maintaining infrastructure. However, some of the board members who have been in positions of power at PGE for many years, and who have overseen the company’s declining infrastructure, include:

  • Robert C. Flexon, Chair of the Board since 2018
  • Peggy Fowler, Retired CEO and President of PGE from 2006 to 2017
  • Nik Blosser, Vice Chair and Vice President of Public Affairs at PGE since 2015
  • Jardon Jaramillo, Treasurer and Senior Director of Investor Relations, Treasury and Risk Management at PGE since 2016
  • Anthony F. Earley Jr., Former Chairman, President and CEO of Xcel Energy Inc. from 2008 to 2016
  • J. Michael Garvin, Retired Vice Chairman of Rothschild Inc. from 2004 to 2016

It is important to note that these are just some of the board members who have been involved in PGE’s decision-making process over the years. It is also possible that other board members have played a role in the company’s infrastructure policy, even if they were not in positions of power for as long.

Ultimately, the responsibility for PGE’s infrastructure policy lies with the entire board of directors. The board is responsible for setting the company’s strategic direction, and for ensuring that the company’s operations are conducted in a safe and responsible manner. If the board has failed to adequately maintain PGE’s infrastructure, then it is ultimately responsible for the consequences of that failure.

Solar Mining

The process of converting photons to fiat currency with the least amount of work and cost.

Currently crypto mining with solar is the most cost effective option.

What’s the most efficient miner right now?

Right now according to https://whattomine.com/miners?cost=0.1&cost_currency=USD&sort=efficiency_desc, the most efficient is the iPollo Mini Plus at 232W an generates about .89 cents per day.

With 6 hours of sun, a 5.91kW battery, 740W PV array, and 2000W inverter, show me how many 232 Watt ASIC miners can I run 24 hours a day?

the steps to calculate how many 232 Watt ASIC miners you can run 24 hours a day with 6 hours of sun, a 5.91kWh battery, a 740W PV array, and a 2000W inverter:

Calculate the total energy generated by the solar panels in one day:

solar_energy = sun_hours * pv_array_power

solar_energy = 6 hours * 740 watts = 4440 watt-hours

Calculate the amount of energy that can be stored in the battery:

battery_energy = battery_capacity * math.ceil(solar_energy / inverter_power)

battery_capacity = 5.91 kWh
inverter_power = 2000 watts

battery_energy = 5.91 kWh * math.ceil(4440 watt-hours / 2000 watts) = 76.42 watt-hours

Calculate the number of ASIC miners that can be run 24 hours a day:

asic_miners = battery_energy / asic_miner_power

asic_miner_power = 232 watts

asic_miners = 76.42 watt-hours / 232 watts = 3.31 miners

Therefore, you can run 3.31 232 Watt ASIC miners 24 hours a day with 6 hours of sun, a 5.91kWh battery, a 740W PV array, and a 2000W inverter.

3.31 * .89 = $2.94/day

$1139 / 2.94 =387.41 days to break even the 82/mo revenue

Battery Sizing

Shopping for AGM batteries for your motorhome, power plant, or solar sump can be a hassle with varying voltages and amp hours and kilowatt hours.

Lifepo4 batteries are still out of reach for alot of folks, and sealed AGMs are still the way to go. Especially with a solar charge controller, AGMs are the best solution for the working class.

With all these different data types, you dont want to cheap out and you don’t want to overspend so how to translate into a real number that you can use to decide whether a battery is the right balance of cost and value?

Stated AH are always underwhelming and rarely accurate when determining value of a battery. kWh of a battery is more accurate but still less likely to be stated for a battery you can actually afford!

Actual kWh is not simply stated AH*V/1000. That’s for suckers.

Real kWH is [(AH*V)+(CCA / 7.25)/2]*V/1000 which is an average between stated and real.

Instead of going by stated values alone, get a more realistic comparison by measuring kWh per dollar.

EX. The real kWh of my system is 5.91 and I spent about 2000 on the whole deal, so DPKW is $2000/5.91KW= $338.40/kwh

The same system with this awesome lifepo4 battery https://signaturesolar.com/eg4-lifepower4-lithium-battery-12v-400ah/ would be 2000-1365 (AGM w/ 3 yr warranty cost)+1997(lifepo4 shipped freight 5 yr warranty) = $2632/5.12= $514.06/kwh

Of course I would rather buy the lithium system, it’s just a higher up front cost for slightly less kwh.
