30A MPPT 12V/24V Solar Charge Controller
Description
Description
-
Ultra fast MPPT Tracking
The solar charger contains an ultra fast MPPT controller. This is especially beneficial when the solar light intensity is constantly changing, as is the case during cloudy weather. Because of the ultra fast MPPT controller, 30% more energy is harvested compared to solar chargers with a PWM controller and up to 10% more compared to slower MPPT controllers. -
Optimal Solar Yield
The solar charger has an innovative tracking algorithm. It will always
maximize energy harvest by locking to the optimum MPP (Maximum Power Point). lf partial shading occurs, two or more maximum power points may be present on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPPT. -
Built-in buffer allows max 25% exceeding rated power input.
Charging modes are available for most common deep-cycle battery types in the market, including AGM (sealed lead acid batteries), GEL, Flooded, and lithium.Use mode is also available for customized parameters setting. - Auto recognition of 12V/24V battery system. Voltage is available to M2420/M2430/M2440 models(lithium battery excluded).
- Provides multiple load control mode options for light based,time based and manually adjusted scenarios and low no-load loss.
- It has industrial grade design with full range of electronic protections, such as battery over-charge, battery over-discharge, PV over-voltage, controller over-heating, DC load short- circuit, DC load over-load, as well as reverse polarity protection for PV and battery sides, etc.
-
Supports RS485 communication with Modbus protocol (RJ12)
Supports parallel charge function of dual units by linking each other with the parallel charge cable (optional accessory, not in the standard package list). - Supports remote display screen for monitoring and operation. Linking through RJ12 port in the controller(optional accessory, not in the standard package list).

Going Solar Is Now So Easy A Caveman Could Do It | 562K+ Views

I show how simple building your own DIY solar power system can be. I focus on the 3 major components of solar. The solar panel, charge controller, and LiFePO4 battery. I show how simple it is to connect them together to get them to work. This is just an intro to solar. Once people understand those components, I think that is a good foundation to move on from there. From there they can go to inverters, switches, fuses, and on to adding more panels and more batteries to build a larger solar power system.

Let customers speak for us
Exactly as described, includes comms cable and battery cables, screen is easy to read, appears to be accurate ah rating. Quality case. Excellent packaging (thick cardboard box with protective card edge strips with dense foam to cushion movement).
Only improvements they can make are instructions don't explain how to mount the rack and handles but does talk about not included stacking kit mounting. And the app isn't particularly well thought out. I understand it's a reskin of the BMS manufacturers app, but it could be a lot better with very little changes.
But overall 9/10, exactly what I needed at the price I needed.
I haven't had the battery long enough to see battery full potential and charging times. Soon though.
Bought this second battery to use in series with the first battery to make 24V battery bank to run my EG4 direct solar 12,000 Btu 120V ac mini split overnight. I can air condition 600 square foot area with just 2-12.8V 280ah batteries in serious. Although we did another video where we ran this mini split overnight with just one WattCycle 12.8V battery and a 120V ac output inverter Keeps area 600 sq ft area 76-78 degrees overnight even with it being 116 degrees outside yesterday. Still have 40-50 percent state of charge left in batteries in the morning when the battery bank is charged up again. I will definitely buy more WattCycle batteries. Have been using for several months now, extremely reliable for me. Highly recommend the WattCycle batteries.
Batteries arrived in good shape & well packed. Came with short & longer bolts which was helpful. I installed 4 of them in a boat as the primary house side. They replace 4 each 210 AHr AGM batteries that were half again bigger and twice as heavy (120 lbs each) as these ~60 lb 314 AHr LifePO4 batteries. This tripled my house capacity & removed 240 lbs of the weight. I added 250A MRBF Fuses to each +positive battery, as well as a 350A Class-T fuse on the overall DC+ side. Additionally, I added a Victron 500A Waterproof SmartShunt to monitor the charge/discharge levels. For charging, I added a Victron Orion XS 50A DC to DC charger for the alternator, and a 40A LifePO4 AC to DC Charger with a remotely activated plug. So far, the batteries seem to be working as advertised.
Had a few issues with shipping due the batteries being so heavy, may have been dropped by FedEx but WattCycle shipped out a replacement. Can’t fault the customer service. Just finished putting my server rack together before wiring it to the inverter.
I needed longer battery life, my old 100ah battery just wasn’t cutting it. With this battery I can run my fridge/freezer 3 times longer without worrying about running low on battery life.
This harness takes all the guess work out of linking your batteries in a series. Just connect all the wires up and plug the ends in and it’s done. They also come with really nice heat shrink connectors to hook up to your main power wires. 100% a must have for a 36v system.
Use to charge Wattcycle 280. Charges in reasonable time. Helpful display to match my Victron shunt and Bluetooth from battery. Added inline heavy duty on/off power switch to better control charging cycle.
Very well constructed, packaged, and documented battery.
