    Connect Alligator Clips to Removable Battery Posts

    Thanks! That's exactly what I did earlier today, with a bit of cushion around the pliers to prevent thread damage. I suspect that the thumb/knob will get stuck like that every time you tighten it down. Have you found that to be the case?

    Thanks, sounds good. Do you have a link handy?

    Connect Alligator Clips to Removable Battery Posts

    I sent the seller a message to see what they say since the charger they sell also uses alligator clips. I'm thinking my best bet is to get screws with hex nuts attached on top like my other battery.

    Connect Alligator Clips to Removable Battery Posts

    That's the problem, the clips are hardwired on the LiFePO battery charger. There is no room to get a clip on underneath the positive cap/knob.

    Connect Alligator Clips to Removable Battery Posts

    Gotta be user error here, I haven't had a battery with removable posts before. What's the correct way to put these posts in? The positive post plastic cap is stuck to the screw so there is not enough room to for battery charger clips.

    Refrigerator flickering lights with EcoFlow

    Thanks @Bob142. I checked with watt meter on the fridge AC plug yesterday. Voltage was 122 on grid, 119 from Delta mini and transfer switch. Doesn't seem like much difference. Unfortunately in my haste to troubleshoot I plugged the Delta mini into AC charging to see if the EPS/UPS/bypass would...

    Refrigerator flickering lights with EcoFlow

    I have a Reliance manual transfer switched used with a generator, Giandel inverter + battery, or AC200P without any issues. I got an EcoFlow Delta mini (x2) and using that source my refrigerator lights are flickering and the power draw seems higher than I see with the other power sources. The...

    12v to 48v Converter Wire Gauge

    My apologies for the odd use case here. I'm trying to charge a power station via the PV input from a standalone 12V LiFePO battery or the 12V battery in a hybrid vehicle in case of power outage. The power station will take 300W 11–75V DC 10A max. So without the boost converter I can only charge...

    12v to 48v Converter Wire Gauge

    Would this 24v converter (240w) be safer? If I enter <= 22 amps in the calculator with same settings used for the other converter it recommends AWG 14, which is what this converter has. But if you enter 23 amps it recommends AWG 12.

    12v to 48v Converter Wire Gauge

    I put the same entries into their app and website, but even with 35 amps and 90ºC insulation it still gives me 12 AWG wire. I had to enter 75ºC insulation to get it to recommend 10 AWG. Am I missing another setting?

    12v to 48v Converter Wire Gauge

    Far from optimal I know, but it's a cheapish way of extending the runtime. Otherwise I have to use an inverter on the battery to use the power station's AC charger.

    12v to 48v Converter Wire Gauge

    I've been looking at that route also. Doesn't have to be 48v but I'm trying to get a higher charging rate than just connecting the battery to the MPPT input (~100w). The power stations I have max out at 10a or 12a for the MPPT input.

    12v to 48v Converter Wire Gauge

    Thank you, title corrected. I can use the proper wire gauge for the add ons but it looks like the short wires built-in are not adequate. I wonder how they can even sell this?

    12v to 48v Converter Wire Gauge

    I'm looking at discharging LiFePO batteries into power stations MPPT. This boost converter meets the voltage requirements but the first review is saying that the input wire gauge will not handle the amperage. I checked and the 32a max amperage looks adequate for 12 AWG with 105 degree...

    Bluetti AC200P (Houston)

    Houston-area peeps, I have an AC200P I no longer need if you are interested. It has only been discharged and charged to 100% upon arrival. Comes with original accessories and extra solar charging cable, lead acid battery cable, and 25a DC RV aviator cable set. I'm selling because I am moving to...

    Transfer switch help

    It definitely works. We are using it for 120v critical loads in grid outage. No, I had an electrician install it.

    Transfer switch help

    @feverdog, I have that manual transfer switch that I use with generator, power stations, and inverter/battery. I'm not nearly as savvy as the DIY guys here but I might be able to point you in the right direction. What advice are you looking for?

    Refrigerator real consumption versus energy guide estimate

    Nice work. What do you guys think of overriding the thermostat/compressor powering off and on? I've seen in gas generator forums it is common to suggest running the fridge for an hour and then not run it for 4 hours. For a battery/inverter I've also seen suggestions to use a programmable...

    PV Switch

    Our plan currently is to go with a Tesla installation, but somebody in the FB Bluetti group posed this question which piqued my interest. She was asking if she could use a 4 kW grid-tied installation, 2 strings of 2 kW, and divert each of the strings from the grid-tied inverter to a AC300 (2,400...

    PV Switch

    Would a residential installer do a grid tied system with a manual switch before the string inverter to route the PV DC to a separate MPPT/battery system for outages?

    Undersized Tesla Solar Install for Backup Power

    Either size system provides enough for the loads, although the larger system would recharge the battery faster and during inclement better, more.

    Undersized Tesla Solar Install for Backup Power

    With ITC, not including the Powerwall: 4 kW: $6,068 8 kW: $12,136 About 10 years break-even for either option, but we haven't been too worried about breaking even since we are getting this for backup purposes.

    Undersized Tesla Solar Install for Backup Power

    We are looking at a Tesla solar installation mainly for grid outages, currently have a generator and some small battery backup. Based on our average electric bill Tesla recommends 8 kW PV and 1 Powerwall. Since we don't plan to offset all of our grid usage we'd prefer to go with the lower cost 4...

    Using a gen 2 Toyota Prius as a generator

    A PlugOut kit might be of interest to you. It won't help run the AIMS but they sell inverter kits that connect to the hybrid traction battery.

    Charging AC200P Bluetti with batteries

    The AC200 Max (August) will have battery inlets. But only for their battery packs I’m sure.

    Charging AC200P Bluetti with batteries

    Would work out better for my application. If AC200P is fully charged, full 700 watt solar input, and charging a 100ah battery. But still not great with the conversion loss.

    Charging AC200P Bluetti with batteries

    Bluetti sells the cable to charge from 12v/24v battery, do you mean something else? I wonder if anybody has tried a boost converter to get to 36v?

    AC200 won’t charge via solar anymore

    My AC200P won't charge from solar now also, but possibly my fault. I had 2 100w panels in series getting 130w so I was disconnecting them to connect each one separately to see if one was underperforming. I left the AC200 cables plugged in while disconnecting one of the panel cables to isolate...
