An AI assistant for inverter, solar and home battery brands

An AI assistant answers inverter fault codes, commissioning and parts questions from a solar or home battery brand's manuals, error-code lists and parts catalogue. Homeowners, installers and new support staff ask it on the website, WhatsApp or the installer portal.

On a sunny afternoon an inverter drops off the grid, shows a code, and the owner searches for it. During commissioning an installer rings your technical line to ask which battery module fits which inverter. Here is how an AI assistant gives them, and where it stops.

In short

An inverter or home battery brand already has the answers in its error-code lists, installation and commissioning manuals, app guides, compatibility tables and parts catalogue. An AI assistant reads those documents and serves four groups: homeowners with a code on the display or an app that went offline, installers commissioning a system, the parts counter matching a data logger or battery module to a serial number, and new staff learning the range. User guides go to a public agent, service documents to a second agent behind the installer login. SimplyBoost, our own product, does this from your documents on website chat and WhatsApp.

Examples

Five questions this assistant answers in a solar and battery network

Homeowner, sunny afternoon: "The inverter shows E-xx grid overvoltage a few times a day and production drops to zero."
Answer: The inverter disconnects for safety when the grid voltage is too high and usually reconnects by itself once it falls. If it happens several times a day for a week, ask your installer to measure the voltage at the meter cabinet.

Installer, planning a retrofit: "Customer has a 5 kW hybrid inverter from 2022 and wants a battery. Which modules fit, and how many?"
Answer: The compatibility table lists the supported modules from firmware version x.y and the maximum number per stack. Update the inverter firmware first if it is older, then pair them in the order given in chapter 7.
Source: compatibility table, hybrid inverters; installation manual, chapter "Adding a battery"
Technician at commissioning: "The app shows the battery discharging while the house draws from the grid. Readings look mirrored."
Answer: The guide gives two causes: the CT clamp on the grid cable is fitted the wrong way round, or it sits on another phase than the inverter. Check the arrow points toward the house and the phase matches the wiring diagram, then restart the meter reading in the installer menu.
Source: commissioning guide, chapter "Energy meter and CT clamp"
Parts counter, installer on the phone: "The owner's Wi-Fi data logger is dead, serial starts with 19-xx. Which replacement?"
Answer: That serial range takes the second-generation logger, which needs inverter firmware x.y or later. The part number is listed, and the order request goes to the parts team with serial and installer details.
Source: parts catalogue, "Communication accessories"; service bulletin on the logger change
New support employee, first sunny week of spring: "An owner with a dynamic contract asks if the battery can charge from the grid at night. What do I say?"
Answer: Explain the modes as the battery manual lists them: self-consumption, time-based charging where the model supports it, backup where installed. Whether it pays off for one household is for the installer or energy supplier to work out.
Source: battery user manual, chapter "Operating modes"
Illustrative examples; the answers come from your own documentation.

Installer in your network	Which battery modules, energy meters and CT clamps fit which inverter	Compatibility tables, installation manual
Technician at commissioning or a service call	Grid settings, pairing order, firmware steps, a fault that keeps returning	Commissioning guide, service manual, service bulletins
Parts counter	Which data logger, battery module or replacement inverter fits a serial number	Parts catalogue, accessory lists, a CSV of part numbers per serial range
New staff in support, parts or sales	Differences between generations, operating modes, registration steps per country	The same documents, through an internal agent

Technician helpdesk

A technical helpdesk for installers on the roof

Installers call your technical desk from the roof or the meter cabinet, during commissioning, with the homeowner waiting for the app to show production. The questions are specific: the grid settings and country setting for a new inverter, the order in which inverter, battery and energy meter are paired, the firmware a battery module needs. An assistant on a WhatsApp Business number, or behind the login of your installer portal, answers from the commissioning guide and service bulletins and names the chapter.

Installers who log in are recognised by their verified email address, so service procedures stay out of the public agent. Where the documents do not cover the case, the assistant says so and hands the question to your second-line engineers in Zendesk, Freshdesk, Gorgias or Slack, with model, serial number, firmware version, code and the full conversation. Installers in Wallonia or Germany get the answer in French or German.

Parts

Parts questions matched to serial number and firmware

Solar and battery ranges change faster than their model names. A data logger is replaced by a new generation, a battery module needs a later firmware, an inverter is swapped under warranty for a newer hardware revision. No answer is safe without the serial number, so the assistant asks for it first and then answers from your parts catalogue, accessory lists, service bulletins and a CSV that maps part numbers to serial ranges.

When an installer wants a replacement CT clamp, data logger or battery module, the assistant collects part number, serial number, quantity and the installer's details and passes the request to your parts team. It does not place the order, check stock or quote a dealer price. Those live in your ERP, which is the custom route below.

Training

New staff learn from the same knowledge base

The first sunny weeks of spring bring grid-fault codes, apps that lost their connection after a router change and questions about battery modes, all at once. New support staff then queue behind the one colleague who knows every inverter generation.

Each SimplyBoost account includes three AI agents, for example a public agent with user guides, an installer agent with service documents and an internal agent for your own team. New staff in support, at the parts counter or in sales ask the internal agent first, and every answer names its source, so they learn the documentation while they work. A new employee who takes a call from a Flemish installer looks up the Fluvius registration step instead of guessing.

What senior engineers know but never wrote down is the gap: ask them for a short FAQ of their most common answers and upload it.

Two routes

Which route fits your questions	AI customer service for dealer networks: buy or build	Crux works alongside your IT partner, never in its place

Rules in NL and Flanders

The rules the assistant has to get right

Registration in the Netherlands. Registering solar panels and home batteries on energieleveren.nl is a legal obligation (Enexis), and since 7 May 2024 home batteries are registered there separately (Netbeheer Nederland).
End of net metering. The salderingsregeling ends on 1 January 2027; until 2030 the feed-in compensation must be at least 50% of the bare supply tariff (Rijksoverheid). The assistant answers from your own explanation and refers a calculation for one home to an installer.
Grid overvoltage. An inverter switches off when the grid voltage reaches 253 volts and usually restarts by itself (Liander).
Flanders. A home battery needs an AREI inspection by a recognised inspector and registration with Fluvius within 30 days. The capacity tariff follows the average of twelve monthly peaks, which a battery can help lower (Vlaanderen.be).
The assistant answers these from a dated country checklist you upload and replace when a rule changes.

FAQ

Frequently asked questions

Can installers use it during commissioning?

Yes. Installers ask the installer agent on WhatsApp or in your portal while they stand at the meter cabinet, and it answers from your commissioning guide, compatibility tables and service bulletins, naming the chapter. If the documents do not cover the case, the question goes to your second-line engineers with model, serial number, firmware version and the conversation.

Can it tell which data logger or battery module fits?

Yes, when you upload the parts catalogue, accessory lists and a CSV that maps part numbers to serial ranges and firmware requirements. It asks for the serial number first. An order request is collected and handed to your parts team; stock and dealer prices stay in your ERP.

How do new support staff use it?

They ask the internal agent what they would otherwise ask a senior colleague: what a grid-fault code means on an older series, how the app reconnects, which registration step applies in Flanders. Each answer names its source document, so they learn the documentation while they work. Your senior team adds what is not yet written down.

Should we choose SimplyBoost or a custom build?

Choose SimplyBoost when the answers are in documents: error-code lists, manuals, compatibility tables, parts catalogues. Choose a custom Crux build when the answer has to come from a live system, such as the monitoring platform for one installation, stock in the ERP or the status of an RMA. The custom route runs in three fixed steps, starting with a €2,500 AI audit.

Can it explain what the end of net metering means for a battery?

Only from what you upload. Put a dated explanation of the end of the salderingsregeling on 1 January 2027, and of the Flemish capacity tariff, in the knowledge base. Every owner then gets the same answer, and a calculation for one home goes to an installer or your team.
