How do you think you can install that much solar on a 35ft sailing boat and still have a viable sailing boat? 1000w is about as much as you see on most sailing yachts up to about 45ft. My 44ft sailboat has 920w. Your loads are also nothing like reality. Why do you think you will be cooking for 3...

It's all pretty academic for me. Since my cells are in a sailboat, they need to be restrained from flying around the battery box. They are 'compressed' as that allows them to be fixed in place. As a bonus, we don't get any stress at the cell terminals. My cells arrived with a data sheet that...

Daly do fail. This happened to a friends Sterling battery. The passive bms is useless. With good cells you don't need to top balance if you use a JK bms. You just let the active balancer do it for you. Not possible with a Daly

My 24v built is 100L fridge freezer with lots of insulation, uses a 45w compressor running 20 mins in the hour. Less that 0.5kWh/day. In the heat of the Caribbean

What are you using it for?

Why do people buy stuff then ask if it's OK? Wouldn't it be better to ask what to buy first?

I just connect the JK BMS and charge the battery. Monitor the cell voltages when you get up near fully charged and see how the balancer gets on. If there are any cells lagging badly behind, connect your charger to that cell. Let the balancer cut off the high cell voltages.

We are on a sailboat. It's a 24v boat. Made no sense to build 12v lithium batteries but total sense to build 24v batteries. That's what we did. 2x24v lithium gives us some redundancy. The starter motor is 24v so we have a pair of lead batteries in series for that. Having everything at 24v makes...

I think the NH00 fuses are also designed to not throw molten metal around. Same principal of an enclosed ceramic fuse surround with silica sand. A very good alternative to class T and a lot cheaper in Europe. About $10 per fuse

My NH00 fuse holder is 135mm long. 160A fuse. Like class T, the fuses and holders get bigger depending on the rating of the fuse. Since I fuse each battery and I run a 24v system 160A for each battery is plenty for me. My largest load will come via the 3kw inverter which limits me to about 125A...

How do you work that out? I have class T on one of mine. It's the larger fuse as I am fused at 225A. The NH fuse holder is shorter and more compact. I have one of these mounted on my other battery. Much prefer the NH fuse

I have two diy batteries. Just saying that no AIOs at to suit that requirement

What if your systemm is 24v. You want a 3kw 24v inverter and way more battery capacity, say 400Ah at 24v. I can't see anything that compares to DIY

Thats w That is what I use. A fraction of the cost of class T but they do the job perfectly with the same AIC capability. It just shows what a rip off Class T fuses are

My understanding is it depends what you are using it for. If you intend to run high inductive loads such as motors found on AC watermakers, a low frequency inverter will be more reliable. If you just want to run resistive loads like water heaters, then a high frequency inverter will be fine.

I would suggest you trace every wire and produce an "as installed" wiring diagram. This will help you understand what you have before you make any modifications or replacements

One thing to consider. Horizontal panels lose about 20/25% of their output compared to adjustable panels.

I would not of thought so. The way they tend to work is, once they hit their target voltage, they hold that voltage indefinitely, dumping excess energy. As long as the sun is there, it would stay at one voltage with no float or absorbtion

They are easy swapped in a diy battery and pretty cheap. About the cost of one cell

JK every time

?

There is more to this problem than a cell balancing issue.

You can't get it 'back in line' with the balancer below 3.4v. At the top of the charge it will be out of balance regardless. Have you tried leaving the battery in absorbtion for an hour at 3.55v per cell with the balancer running?

Looking at your first image. You have an average cell voltage of less than 3.0v. Why are you balancing at these voltages? You don't want the balancer activating until 3.4v as a minimum. You can see the balancer is working in the image. You need to sort this out as you are not top balancing with...

We use up to about 100A at 24v. It's spread over a pair of lithium batteries with their own fuses. A tiny loss. Most of the time the loads and charging currents are way less.

Storm in a tea up. Its fixed with new software update. Andy wouldn't make much money if his videos were boring?

We haven't gone the wakespeed regulator route yet for our soon to be fitted 24v 155A alternator. We are on a boat somthe 450cc twin cylinder diesel genset can kick out over 100A at 24v for less than 2 litres per hour

You guys in the USA have a USA centric view. Its not the whole world. A quick Google search and Victron made $23M in profit for the last year. What other solar products company in the US is doing that? Victron supply equipment to rural communities in 25 African countries alone. Maybe they just...

You are the chosen one?

A friend had one fail in his Sterling battery after 2 years. The cells would never balance due to the crappy passive balancer. The battery would shut down due to a high cell. Never use Daly if you can buy a JK BMS. So much better

Is this for a main earth point for the solar or lightning protection? When we have designed lightning protection systems we often have multiple rods in a mat. The ground resistance is measured and rods are often up to 4 metres long and numerous to minimise resistance

For boats and RVs, 24v makes a lot of sense. Cable sizes are about 1/4 of the cross-sectional area for the same volt drop as 12v. Lots of kit is already available in 24v due to trucks running 24v. Fans, led lights, fridges etc. The cable runs are not super long in an RV so 24v works pretty well...

I am not referring to the latest JK BMS. I am referring to the previous version. It's tried and tested. Reliable and cheap. If uou watc. Andys videos you will know that he still believes the older version is the best FET based BMS, until such times as he proves the new version

You will have to search through the recent ones

Have a look at off grid garage Utube channel. He revues all the BMSs in detail. The PACE didn't rank well. The JK BMS is his preferred BMS.
