Steps You Need To Take Next

As early as this February, wireless carriers like Verizon and AT&T will stop supporting more than 22 million 3G devices—including the reporting equipment within many solar photovoltaic (PV) systems.

Depending on the component makeup of that particular system, this can be either 1.) A revenue-grade meter or 2.) A CDMA/GSM modem contained within certain inverter models. 

If you’ve reached this page, your solar system contains equipment needing replacement in order to continue receiving SREC payments.


365 Pronto is the technology and logistics partner selected by SRECTrade to conduct this replacement work for all solar PV systems under trading.

Have both?

The meter is what your solar system uses to communicate your solar output with SRECTrade. Without this meter, we cannot determine how many SRECs to mint to you.

For cellular-based monitoring to function, solar inverters contain a modem operating on Global Systems for Mobile (GSM) or CDMA, a radio network used by wireless carriers. These networks are more commonly referred to as 2G and 3G and were widely used in the early years of cellular communication technology, with CDMA being the predominant network in the U.S. 

This page is the entry page for the SRECTrade replacement program. Please scroll up to review and assess which scenario applies to you.

Wireless communications protocols become obsolete over time, and the wireless carriers (Verizon, AT&T, etc.) are phasing out old networks (2G/3G) in favor of faster, upgraded networks. Many solar systems installed more than three years ago likely have equipment designed for the network technology of the time (2G/3G).

365 Pronto is our technology and logistics partner. It is a technology platform company matching asset owners (you) with an on-demand qualified workforce (local service providers) through automated DNA match technology. Because of its unique model, it can service the entirety of SRECTrade’s systems under trading.

Through our partnership, we were able to negotiate a special lower-than-market price just for Massachusetts SREC Trade customers. This price includes all parts and installation, plus a five-year data plan. You should act now, because next month, 365 Pronto providers will be conducting work in your area. If you reserve your modem/meter replacement slot by Saturday, January 8th, 2022, you can secure a 20% in-market price discount on your equipment and installation.

Yes, you may contact your installer to ask about having this work performed. However, providers who are not part of the 365 Pronto network may not be able to guarantee the same price. This is why it is important to book your meter/modem replacement with 365 Pronto before Saturday, January 8th, 2022, and reserve your discounted price.

Due to supply limitations, we expect that your meter or modem will be installed between February and March 2022. Once your 365 Pronto service provider has your equipment in stock, they will reach out to you to schedule the installation. At that time, 365 Pronto will process your payment for the installation. In some cases, the homeowner does not have to be present during the installation. However, if the unit is located in the garage it may be necessary for you to be present during the installation.

Meters will be sent to the local assigned provider to deliver and install in the same visit.

Modems, on the other hand, will be sent directly to your home. When the modem has shipped, you’ll receive a USPS tracking number per email so you’ll know the status and when it will arrive.

No. Once your new meter/modem is installed, it will begin to communicate your solar output with SRECTrade as normal. If you have questions about your account, please email ma.renewables@srectrade.com.

We understand that there is a delay between when your output is recorded and when your SRECs are minted. We will provide email confirmation to let you know that the system is working. If you have questions about your account, please email ma.renewables@srectrade.com.

The existing Locus LGate 120 meter will be replaced with an R-LGATE-CATM1.

Modems will either be replaced with a SolarEdge CELL-A-R05-US-S-S2 or SolarEdge CELL-B-R05-US-S-S2 depending on the inverter type.


Installers do not have a choice in the type of replacement meter or modem they install.

The R-LGATE-CATM1 is the dedicated replacement for the LGate 120 meter.

The SolarEdge CELL-A-R05-US-S-S2 or SolarEdge CELL-B-R05-US-S-S2 is the dedicated replacement for the modem.

Both replacement parts are cellular-only and do not support an internet/ethernet connection.

If, on the rare occasion, a customer wishes to cancel an order, they should submit the request to support@365pronto.com.

The security of the 365 Pronto platform and website is paramount, and we treat customer information with the utmost care. While we have not received any official reports of notifications related to the security of our site, anyone with questions should reach out to support@365pronto.com.

Currently, we offer chat support via the website and email support. Although we can help a customer with the process, you do need to access our platform online to purchase their meter/modem. You can access the sign-up wizard from any browser on a phone, laptop, or device of your choice.

Your meter/modem will continue to monitor your output; however, it will no longer communicate directly with SRECTrade after the 3G sunset, which is scheduled to happen as early as February 2022. If you have specific questions about your SREC account, please contact marenewables@SRECTrade.com.
