  • Here's a strange question! If you have a battery bank hooked in parallel (3 B.B), here the question. If I have my charge controller hooked to +(1st) and -(3rd) batteries, does a secondary battery charger need to be hooked in the exact pattern or can I hook +(3rd) and -(1st) batteries?
    I was discussing residential solar with my nephew. He is looking at storage options so he can use his solar production in peak hours and grid during off peak hours. I mentioned LiFePO4 batteries. He said he has been researching Vanadium Redox systems from Australia and NZ. Are you familiar with VR and if so how do you think it potentially compares to LiFePO4?
    Hey Will,
    Wondered if you were interested is showing us how to setup a REC-Active BMS with a WakeSpeed regulator for a 12 volt system using a Nations 280V aux. alternator ? I know of several guys trying to do this and having lots to problems that need to be solved.
    HI WILL MISS UR UTUBE PRESENCE. SOME GUYS AT THE FORD DELASHIP ASKED HOW I LEARD TO DO ALL THAT WIRING AND CIRCUITS AND STUFF. I POINTED THEM IN UR DIRECTION. UR VIDS HELPED ME FIN ISH MY SYSTEM. ITS NOT PRETTY BUT IT WORKS. : ) APPRCIATE UR EFFORTS STAY SAFE! ALLAAHU AKBAR!
    How do I add a Battle Born battery to my Ecoflo Delta? and what else do I need to purchase? Does this make sense? I know I can add another Eco flow but just looking at.......More Power....
    Thank you

    in 2013, I put together a small pole mounted solar array of 5 100 watt panels, a Xantrex Pro 2000 watt inverter and a Schneider C-35 Amp charge controller with a bank of 6 Duracell Deep Cycle Marine 12 Volt Batteries to power my freezer in case of a power outage. Batteries have wore out and died.
    Can I salvage any part of this system? What changes do I need to make/purchase? I need help.

    Replace the batteries and keep all the rest of the system. You might get Deep Cycle batteries again, which will likely last only 6 years again. Lithium cost more money but last a long time. Look at Wills Resources or DIY Solar Blueprints and get the batteries he recommends. Lithium should last about 5000 cycles, so if you're only waiting for power outages your Li batteries might last 20 +years?
    Hi, I am building a 16 Fortune cell 400Ah, 12 volt battery. I am looking for a very reliable BMS. Has anyone used the REC-BMS? Any recommendations are welcome.
    Hi Will! I saw the YouTube review on the new ENERGIZER 240wh LiFePO4 MPPT Solar Generator by HOBO Tech, but I want to hear your expert opinion. It may be as good or better than Jackery 240, but I want the JE300, which is out of stock till Dec.? Maybe this Energizer is a viable/better option? Please review & let us know; Thank you!

    My name is Brandon. I'm located in Kentucky: Daviess Co area.

    Can i put x2 Renogy hybrid gel batteries in the house. They will be in the utility room next to the back door. I tried to put the complete post but would not let me for i have more questions i want to ask you. I have read your book many times and you are person that has lots of knowledge.
    Has our group been hacked? For the last few days, my email has been bombarded with these notices. When I click on them, I get the Opps not found messages. Anyway, I thought I would bring it to your attention.

    He is signed up for email notification and all of those were recent spammers that were banned.
    I am hoping for a video on charging lithium batteries with a 12 volt aux. alternator, maybe a 280 amp. Nations alternator.
    A video on transfer switches might be interesting. I'm going to be running some things off grid and some things on grid plus experiment with different combinations. I should be be able to really tweak and balance the load part of the system as my small system won't run everything.

    Hi Will, planning on buying a solar array for my MPP pip 5048mgx 48v system. what solar array can you suggest to be use here in the philippines. And how many watts. thank you much.
    Love your videos. BTW, you might find the PVEL solar test labs and scorecard interesting. PS: could you do more tests on the impacts of shading?
    will, need direction on attaching a 14s 48v bms to 48v lg chem batterry modules, there are 2 sets of wires under the metal cocer. 1 has 10 wires and the other has 16 wires, the bms has wires for 14 cells, don t want to mess things up
    Hi all. I've got a battery bank that has very small terminals. Like 8 mm screws. 16 Lifepo4 90ah 3.2 cells. I'm I going to have problems with bigger loads.
    Hi Will,

    I started out building 2000 watt 24v system but wanting the system to grow, I mostly did the 4000 watt system.

    I will purchase the following:

    5 Solar Q-cell 390 watt panels

    60 Amp Mppt SCC is Ampinvt 12v 24v 48v 150vdc input 3400 watt

    Inverter and charger:

    SUNGOLDPOWER 3000W Peak 9000W


    batteries are SOK 100ahr.

    And other stuff you suggest on the plans site.

    Thanks for your book and ll your help.
