    keep LifPo4 batteries charged until needed

    charged overnight and up to 54.7V - I am pleased, relieved and grateful to you all for the practical advice. I'm gonna shut down the charger and set up an inverter to cycle through a discharge/recharge on a regular basis. I have 8 flexible 12V panels on the roof of my '64 Airstream travel...

    keep LifPo4 batteries charged until needed

    so far so good... I am using two 27VDC 22.2A wired in series and verified 57.3 VDC into a Victron SmartSolar MPPT 150/35. The VictronConnect app is showing 57.4V and between 0.1 and 0.2 amps and battery Voltage 46.66V current 0.10A and State Bulk. I was sort of expecting to see amperage...

    keep LifPo4 batteries charged until needed

    indeed, and just in time... my 57.3V seems to be nearly ideal to start re-charging. many thanks for the guidance!

    keep LifPo4 batteries charged until needed

    That's encouraging...My battery string is at 46.2V (and my 48V power source is 57.3). How do I determine when my battery is below 40%?

    keep LifPo4 batteries charged until needed

    I have an off grid Airstream project and want to keep my 48V LiFpo4 battery string charged while I rehab the travel trailer. I assembled a 48V DC power source and have the Victron MPPT 150/35 solar controller. Will I damage something if I use the 48V power source into the MPPT controller to...

    Cheap 4kwh LiFePO4 batteries from Battery Hookup

    would it be possible send the voltage from a MeanWell PSP-600-27 power supply into the PV of a Victron 150/35 solar charge controller to charge a BYD battery bank?

    Cheap 4kwh LiFePO4 batteries from Battery Hookup

    subscribe! doing my first solar power system on a '65 Airstream "project" I have two BYD battery banks that I am (was?)planning to wire in series for 48v. I have 8 12V 100W solar panels that I plan to wire 4Sx2P for 48V input to Victron MPPT 150/35 SmartSolar charge controller and output to...

    questions about inverters for a solar power system with both 220 and 110 AC

    thanks for the reply... much appreciated I have a fair knowledge of household electricity but this is my first off grid solar project. I'll be mindful of keeping the 110 VAC loads distributed as equally as possible between the two hot legs.

    questions about inverters for a solar power system with both 220 and 110 AC

    This is my first post here and I will be building a system from scratch to go off-grid in a '65 Aistream project. I am considering a mini-split heater/air conditioner and the most efficient models run on 220VAC-240VAC. I'm assuming that the 220VAC out of an inverter is like residential 220 VAC...
