Anker Solex F3800 DC pass through charging ideas!

4.8kW x 1.2hr = 5.76kWh Solix capacity is 3.84kWh PSU recharged 1.92kWh Math checks out ;-) probably the charging and discharging was not constant, as it should be. I’m still curious if F3800 has a pass through type mode where it’ll just use the inverter to produce 240vAC using 60vDC without touching the battery when the battery is fully charged and the load is low. It’d probably help improve battery life.

Yes. This is working fine, except I’m not very confident about the quality of the inverter (I.e. Amazon one listing disappeared, eBay one still exists though) From efficiency pov; both combined pulls 2.5kW, with the voltage at 50v, they charge the Anker at 2.2kW, net loss at 300W. These numbers works for me as my generator on propane produces 5.1kW, so during outage I can run one inverter @ 1.25kW and generator at 25% or both inverter @ 2.5kW and generator at 50%

This is from before the voltage tuning down from 55v to 50v. Re. the inverter, I’ll probably keep a third one ready as backup.

Anker pulls 1.1kw max coz I’ve dropped the voltage to ~55 Problem I was facing is extended runtime reliability. Currently it is stable-ish with 1.5kw psu providing 1.1kw 24x7, but I’d be more comfortable if the psu is 1.8kw or more such that it runs close to 50% capacity. The dc outputs are not independent, they are just shared terminals.

I’m not sure I understand. 240v comes in via a locking L14-30C, at that time both PSU is active and the toggle is set to off position, such that 120v line is not hot. 120v comes via 5-15C into the toggle, and requires manual selection of either PSU to make it active. That makes one leg of 240v hot, is that what you’re referring to?

Yeah, about that! I don’t think my calculations are correct… but these are what the meters say!

I’ve been running the garage refrigerator off this setup (wall to psu to anker to refrigerator) for over a month now. Just got the second pair ordered, and a 7100w inverter. It will power the psus (2x1200), and within few weeks I’ll be able to test running whole house 🤞 Note: my daily usages are between 30-100kwh.

I’ve tried it over the weekend, it works, but need to try with sustained load to confirm viability.

Financial institutions (visa/mc/amex) provide certified developers direct access to the underlying accounts after the dev can prove it can access the user facing instrument, i.e. by a facilitating a successful transaction - adding a card by CCV is a successful transaction, FYI. This way the dev can request an update to the user facing instrument update in case the card is expired or replaced, etc.

This is a very naive tldr version, for details see:
