Remote Monitoring / Control via mobile App.The models closer to the $200 mark may also include bonus features like these that you may want to consider: My Top 5 Battery Monitoring SystemsĪll of the battery monitors listed will have the basic monitoring features previously mentioned. Some systems may take it a step further with more sophisticated SOC algorithms, but all are based on measuring current flowing in and out of the battery bank.
The battery monitor should now show a SOC of 95%. After one hour 5Ah is added back to your remaining capacity. Now let’s put a 5 Amp charge back in your battery. If you draw 10 Amps from your battery for one hour (10Ah), the SOC should read 90% (or 90Ah) remaining. Charge current coming back in from a battery charger or solar is ADDED to the available battery capacity.ĮXAMPLE: A 100Ah battery charged to 100% has a 100Ah of available capacity. Here’s how it works at a very basic level.Įlectrical current (Amps) leaving the battery to power your gear is subtracted from the available battery capacity. The control unit takes the current measurements over time and converts them into Amp Hours.įinally, the computed Amp Hours are either added to or subtracted from the available battery capacity. Those measurements are sent in real-time back to the control unit. The shunt measures electrical current as it flows back and forth across it. Here’s an article explaining Amp Hours if you’re not sure what that means. So the battery monitor first needs to know how many Amp Hours of energy your battery bank can store when it’s fully charged. How Battery Monitors Calculate the State-Of-Chargeĭeep cycle batteries are rated in Amp Hours (Ah). It measures all energy flowing in and out of the battery and passes that data back to the control/display unit. Thinking under $5K for sure.With most battery monitors, the shunt is a separate device connected between the battery and the rest of the system. I guess I want to keep the hardware costs below an additional $4-5K, at the max. I do want something I can connect and manage from afar. I guess I like it as that's the last one I've seen explained.?
Right now liking the idea of a Mpp 5048 240 volt and a transformer for 120V. I didn't expect to put them all into service right away, thought having same type spares would be good. I'm on the fence but am thinking a pallet (24-30) of used 250-300 watt panels as the shipping to Bahamas is crazy, so a pallet costs almost as much to ship as 4 panels. I can get by with less than 10KWH/day if the grid is down, just not as comfortable as I'm used, to but I know it's only temporary. I am replacing my 30,000 btu window shaker ac's with 2 good mini splits, so that number will get much better. I don't believe I will be adding batteries, so I'm only limited in that way right now. My battery bank is 4 x 200 AH 12Volt LiFePo4's. Thanks!Ĭlick to expand.I want to be able to power as much as I can when the grid goes down here (which is a lot), I don't see powering my mini-splits 24 hours or anything close to that. I know I can sell everything easily where I am, I just don't want to keep doing this wrong over and over. My recent purchase of a PD charger/converter was probably rushed into, as the AIO will hopefully replace it? So, my big question is, can I get an AIO that would provide me with the remote monitoring and control, or will I still need something like Raspberry Pi for the monitoring and a battery protect? I have 4x200 amp hour LiFePo4 batteries and at the moment a 12V 1000 watt inverter, just to show myself the possibilities available and I'm excited to go all out now. I've gone down so many rabbit holes here, this old timer's head is spinning. Someone suggested I get Raspberry Pi, someone else mentioned I need a battery protect. I don't want to make any more redundant purchases.
Very soon upgrading to a larger 4000W/24 or 48V AIO and buying a pallet of 250-300 watt panels. I don't want to keep buying the wrong things as I've read so much about different ways of doing this. I just purchased a Victron smart shunt (as many have suggested), and want to monitor and hopefully control my system over the internet from home 1200 miles away.
