The Renogy M1 can work without an internet connection, but it can't transmit data to a mobile phone, so it can't be monitored remotely.

I'm very sorry. For our 3000W inverter, only REGO series is equipped with Bluetooth communication, if your inverter is a REGO series 3000W inverter, you can achieve Bluetooth communication, the rest can not!

Thank you for liking our products! If you have any other questions before you buy, please let me know and we'll be happy to answer them!

Thank you for your review and also for your knowledge of our products! It is true that for Li-ion batteries our controllers do not define the float stage. But our controllers need to maintain a low current charge in this state for LiPo to keep the battery charged and counteract the self...

Can you tell us the SKU of the batteries you purchased? If it is our product and supports replacement studs, we can give you the relevant dimensions of the studs.

Can you send me a video of the connection in action? So that I can determine the problem.

That's what we recommend.

In low temperature environments, the VOC of PV increases as the temperature decreases

Hi, I'm very sorry for the bad experience. From the picture you uploaded, at this point our controller recognises a voltage of 14.3V, at which voltage the controller considers the battery to be fully charged. So at this time the controller will enter the float charging stage with a small current...

This is not recommended, it is recommended that you install the PVs separately on the 2 MPPT controllers

1、Can be used 2. The difference between lithium batteries is mainly the difference in the battery cells, but this does not affect your ability to use our products 3、No need for additional MPPT controller

This is the voltage at which the PV will operate once it enters the controller. This is normal. The voltage you are calculating is the standard voltage of the PV after connection and not the operating voltage

I am very pleased that you are using our products, if possible can you give me the wiring diagram of the system? We will give you suitable advice based on your wiring diagram.

Press and hold the "→" button on the controller to observe the icon at the bottom of the LCD screen of the controller when it flashes, it means entering the setting interface, then adjust the battery type to USER by using the up and down buttons, it means entering the USER mode

From the PV parameters you have provided, this product is not suitable for use with our 200W product

The battery cell voltage error within 0.2V is normal, it does not affect the use, please feel free to use

It is recommended that the BOOST voltage be adjusted to 13.8V

Hello It should be noted that our batteries are put into sleep mode after 24 hours of non-use in order to reduce the self-consumption of the battery and to protect the battery power. As for the situation you mentioned, it is presumed that the battery is at full charge at that time. This is...

The MPPT charging phase, which refers to constant current charging, means that a high current charge is used to rapidly increase the voltage of the battery. Of course our controller is not always in the MPPT phase, it will adjust the charging phase according to the actual battery conditions...

1、Do you connect or start the load in this state? 2、Please test the voltage of the BAT port on the controller and tell the result

Thank you for liking Renogy's products. From your needs, although you need a controller with MPPT technology, we would recommend you to buy our WND10 controller, which uses PWM charging technology, but it really meets your needs the most

If you wish to change your charging parameters, we recommend that you use the "USER" mode on the controller to do so. For the calibration of the battery SOC we recommend that you raise this parameter when setting the battery charge parameter, at which point the battery is fully charged to...

It's funny to answer this question for you, if it's convenient, please tell me the specification of your current battery (voltage & capacity); and how the battery is connected, then I will recommend our lithium battery for you

Dear customer， We have received your feedback. Thank you for contacting Renogy. For solving your problems more timely and efficiently, we suggest you can submit a case through our Help Center Portal (links listed below for specific locations）for help. If you have previously submitted a case...

Perhaps it would be more helpful if you could draw a picture of the way you are wired and show it to us to help us identify the problem At the moment, from your description, it seems that a 60A fuse is not sufficient for your needs and we suggest that you replace it with a 65A or 70A fuse.

This is because the voltages of the PVs are summed up after the series connection. This equates to an increase in voltage

I am very sorry to have troubled you. I would like to clarify that the SOC on our CC is calculated according to an algorithm and there is a certain amount of error in the values so it may not be accurate. If the SOC displayed by DC Home is not accurate, we suggest that you adjust the battery...

Very sorry to hear this information from you, from your description and uploaded pictures, it is presumed that the PV voltage is too low causing it not to charge. Suggest changing the connection of the PV to series

First of all thank you very much for liking and approving our products In view of your electricity needs, we regret to inform you that we do not have enough systems to meet your daily electricity consumption for the time being.

We are sorry to hear about your confusion regarding the use of our products. If possible, could you provide us with a diagram of the wiring of your system so that we can identify the problem?

Thank you for liking our products. Our 100W flexible components are suitable for use in caravans. You can choose the right number of PVs to install depending on the size of your car roof. If it is convenient, you can tell us the daily electricity consumption of your caravan system and we can...

Hi, AH. Since the max. solar input voltage of our 50a dcdc (with mppt) charger is 25v, you only can connect your panels in parallel. Hope it is helpful.

Hi, Prerunner777. Thank you for your feedback. We have checked with our technical support again about the problem. We do not suggest batteries with heating function are used with batteries with no heating function. When the temperature is under zero temperature, the batteries with no heating...

Thanks for your advice. We have given feedback to relevant team to pay attention to this issue. We are taking some steps to make corrections. Any further advice, you can also contact us by support@renogy.com ?

Sincerely apologize for your experience. Could you provide your ticket number or more information so that we could contact customer service team to remedy this? Many thanks.
