Product Description

Zero Export Package – Total Control for Non-Export Systems

Need to meet Zero Export requirements with inverters that don’t support it natively? The Sponge Zero Export Package is your turnkey solution. Built around the Sponge EMC, this kit includes everything you need to actively limit grid export and unlock compliance, savings, and smarter system behavior.

Ideal for jurisdictions with feed-in restrictions or interconnection limits.
Especially useful for mixed-brand inverter systems or retrofits.

  What’s Included

• Sponge EMC (Base, Pro, Pro+) – Intelligent on-site controller with built-in Zero Export logic.
• Revenue-Grade Energy Meter – For real-time export tracking (CCS recommended).
  
• Current Transformers (CTs) – High-accuracy sensors for reliable data (AccuEnergy recommended).
  

How It Works

Export Limit Control is a standard feature of the SPONGE EMC. It calculates the difference in real time and issues power setpoints to the inverter(s) to prevent excess solar from feeding into the grid.

• No more backflow.
  
• No more regulatory headaches.
  
• Just compliant, optimized performance.

How to Build your Zero Export Package

1. Speak to your Frankensolar sales rep to determine if your inverter requires 3rd party control for export-limit capabilities. Some brands which have inverters requiring 3rd party control include:
   1. Solis,
   2. Sungrow
   3. Canadian Solar
   4. Growatt
   5. more…
2. Add your chosen Sponge EMC to your Frankensolar Webstore cart.
   1. Sponge EMC Base (For Projects under 30kW AC)
   2. Sponge EMC Pro (For Projects over 30kW AC)
   3. Sponge EMC Pro+ (For Projects Requiring additional uptime and physical security)
3. Add Sponge - ZeroExportControl Commissioning Fee to your Frankensolar Webstore Cart.
   1. For projects under 30kW AC, commissioning is free. SKIP this step.
   2. For Projects over 30kW AC, Add Commissioning to cart
4. Select a compatible Energy Meter and CT from the Frankensolar Webstore
   1. Consult with Frankensolar Sales Team for project-specific recommendations

What Commissioning Services am I paying for?

1. Sponge will reach out to you directly to onboard your project SLD.
2. Sponge verifies communication design plan for project and makes recommendations for optimized communication (RS485 vs. Modbus TCP)
3. Remote Configuration of the Sponge EMC to communicate with all relevant devices (Inverter, Smart Meter, CT, Battery, etc).
4. Sponge monitors project for first 2 weeks and makes performance enhancing adjustments according to the specific dynamics of the system
