My second Video documenting my project step by step configuring Cheap high quality Lifepo4 cells. I did my best to follow the advice of a trusted expert with several years of experience and who is a marine electrician. Charger settings are detailed. RJ Energy Lifepo4 cells are balanced. The...
Most of us will get a 30% credit for 2019 project expenses. How to use turbotax to calculate your credit and look at rules to maximize the solar tax credit for your DIY Solar Install You may want to review all this content with a tax professional. This is for 2018 but the 2019 should be almost...
Will just did a video showing who to add a remote BMS switch to an older inverter charger. This was perfect timing for my project. Shutting off the inverter at the switch makes life a bit easier because we don't need to use high amp expensive contactors / relays. In this video I go into a bit...
I just finished debugging a my neighbors boat electrics with many bad connections. I made a video of who I trust to teach DIY wiring. Also who do I trust as a supplier.
It would be interesting to see who you trust in your marine electrical projects and provide good value
Here is my video on...
I was able to lift and install all 7 385w panels on the roof by myself. The design shown in the video was unchanged. I think the most critical thing to realize is that you should test your setup before you hoist a live panel. I used a plywood as a "test panel" with the approximate dimensions...
Another Blue Sea ML-RBS Circuit Experiment. In this video, I make a modification to the very simple and brilliant SY Destiny circuit in order to interface with the ElectoDacus TLP187 Optocouplers 150ma max. I needed to use an off the shelf $6.00 12v 4 x relay module triggered on the low side...
I have lead acid for starting. I kept my shore charger and alternator the same and I am using a Sterling Battery to Battery charger. Repost from other v1 diy forum. This video goes over the entire system I have been using on trips this summer.
I am just trying sort out my terminal and BMS connections on my new RJ Energy cells that are popular here. I need to order some longer screws I think. In this video I review possible issues with the short screws. Maybe you all could let me know what your challenges have been with these cells.
The reasons why I changed my mind and did not use the cheap Amazon grid tie inverters. I think most of us should at least consider our options and the risks we are taking by not implementing UL inverters. You can still DIY a UL system and your family will likely be safer.
I got some Blue Sea ML-RBS. I'm using some a N type MOS FET module to disconnect the battery in the case the BMS disconnects the Negative wire. I also have implemented a low voltage and high voltage disconnect on the extreme high and low range. I really like these battery switches but they are...
Proposed wiring plan to integrate my inverter onto my Lifepo4 4s Calb 180ah Pack. I am migrating off my lead acid batteries and am going to keep 1 group 27 starting battery and am going to use the Victron SBP to direct connect the Lifepo4 battery to the inverter bypassing the bms. However, I'm...
I have a few videos on this bms I’m using on my boat now. You can change set points and best of all read your amp counter. Mine is 80 amp but others are higher output that were not available at the time.
I'm getting a bit frustrated because I'm finding many chargers are not custom programmable and they charge to 14.4 vdc pack voltage and my Calb 180ah charge cutoff at 3.6vpc or 14.4 pack voltage. Rod at Marinehowto.com has this chart...
Most Solar projects cost hundreds of dollars. Not this one. You can learn a bunch and spend very little. The Blink Cameras are cheap insurance I think.
Here is a detailed video of my project. I was lucky and had all the parts.
In this video I'm proposing an alternate solution to the popular cheap Amazon grid tie Inverter. This system is much more expandable and converts easily to a permitted system if you insist on not pulling a permit. It is water proof and is not as likey to blowup / melt down.
Here is my video...
Short answer : Best Practice is to have a separate voltage sense wire on your chargers (solar and shore) and voltage regulator. Read this https://marinehowto.com/alternators-voltage-sensing/
Lifepo4 has a really flat charge curve and then it climbs rapidly. Having your charger know the battery...
SY Destiny has published a Simple Latching Relay Driver Circuit schematic that he has been using. I used a bread board to test part of the circuit and I am trying to understand the circuit with Blue Sea ML-RPS 7000 and 7702. I welcome any comments. This circuit has been know to work with the...
I have my house loads connected to he Victron SBP for LVD at a set point above my bms. Here is a video where I do a bench test. The SBP LVD set point is programmable and necessary for lifepo4 so we don’t kill our batteries.
Perhaps the best (safe) way to add Lifepo4 to your boat will be to charge your lithium bank with a battery to battery charger. This way you can keep your alternator and shore charging system the same as I have. However, I believe in shutting off the charger a conservative set point of 13.8v...
Here is a link to a video that shows how to waterproof electronic PCBs. I have a few modules and voltmeters I am waterproofing that are not marine so I needed to waterproof them. I used clear fingernail polish as shown in this video.
Could I hook 2 Modified sign wave inverters to Line 1 and Line 2 after disconnecting the grid with enphase iq 7+ inverters if I was willing to dump load using a heater. Or do you all know a simple way to phase sift to dump production. I know the enphase inverters need to be regulated when my...
Some wiring details and testing I did to prove to myself that the wiring was good before the panels and microinverters were installed. I use a voltmeter to test stuff out and show what a normal system looks like from a voltmeter perspective. I also propose testing of the Q cable. This is for...
