    Low frequency vs High frequency inverter for mobile detailing van

    Yes, the 100ah. 2 to 3 hours run time would be more than enough time as the washer is used for around 20 to 30 minutes of continuous use per detail max with 2 to 3 details a day max and I plan on eventually running panels on the van roof.

    Low frequency vs High frequency inverter for mobile detailing van

    I don't think a soft start option will work due to the need for instant power when it comes to pressure washing. I did read somewhere that there is an on board capacitor so maybe I look more into that and see if that keeps surge draw at reasonable levels. Also, I may end up pluging the washer...

    Low frequency vs High frequency inverter for mobile detailing van

    I know the continous draw is around 14 amps but I can't find any info on the surge rating. l just don't want to run the high frequency inverter and find that it's not able to provide sufficient power.

    Low frequency vs High frequency inverter for mobile detailing van

    I am starting a mobile detailing business and I am currently working on a van build. Instead of running a gas generator, I will be powering my tools with a 48v server rack lifepo4 battery with all in one inverter charger. My main concern with the system will be the decision to run a low or high...

    Thermal efficiency of lifepo4

    This past weekend I went camping where the temp dropped to 35 F one night. When I tried to charge my bms prevented me from doing so as it is set to prevent charging below 5 C. Good to know my bms works as advertised haha (temp reading of 2.5 C). This got me thinking of the thermal efficiency of...

    Finally found a LiFePO4 BMS with Low-temp Charging Protection

    I have the 80 amp version of this bms and it has worked great for me. I was having some issues with the BT connection in that my galaxy s10 was dropping signal quite often. I ended up using an old s4 I had laying around it it worked flawlessly (probably something to do with the s10s low energy...

    Running Large Inverters w/ Relays: Not a good idea? I have 3 alternative solutions

    So if were to use this method of connecting my inverter (which I prefer the most) and I want to have a shunt for capacity monitoring, wouldn't I want to place the shunt between my main negative and the b- of the bms with the inverter (-) connected to the load side of the shunt Here you said. If...

    200aH 12.8V Portable Solar Generator Build w/ 400W panels

    Nice, clean build. Plan on making something like this when I own a home. Great mobile power unit. Do you have any pics of the solar panels? 400 watts for less than $400 and foldable... sounds amazing. I paid wayyyyy to much for foldable panels from Acopower but they are super handy on the road...

    My first solar generator build

    Thanks for your help and insight. This is what I love about working with electrical components. There is most often an exception to the rule or a workaround as long as you know what you are doing. Now, to decided if its worth the cost of a new BP or just run a remote on/off switch. Most likely...

    My first solar generator build

    I remember Will briefly mentioning the change to the Victron BP in rush issue and thank you for letting me know about the issue. I like the remote on/off solution to the problem but for my purposes I rarely have the need for an inverter as I use this case for camping and festivals. The only time...

    My first solar generator build

    So with the BP I am aware that it is unidirectional. On the In/battery side, I have two 10awg wires running to the battery, a single 10 awg wire running to the mppt, and another single 10 awg running to an auxiliary dc charge port (anderson pp where I connect a dc power supply to charge). I...

    My first solar generator build

    The case is double walled so I used short screws to catch the inner wall and took extreme care not to puncture the outer wall. I wasn't exactly perfect with everyone of them. A couple of them went through just enough to raise the outer part of the case but barely noticable and no gaping holes...

    My first solar generator build

    Outer: 19.78" x 15.77" x 7.41" Inner: 18.06" x 12.89" 6.72".... Going for a revamp of my system at the moment. After watching Wills video on these cells, I realized that my cells are used and I could be getting more power out of the same size (150 ah).... rookie mistake haha. Going to purchase...

    Blue Tooth BMS module

    There are many options on aliexpress for a bluetooth bms. I use this particular bms and I love it. Allows me to control a vast amount of parameters and even has temp controls for charge and discharge. I would provide a link but I couldn't find this one. I dont think this specific model is sold...
