EG4 FlexBOSS21 Hybrid Inverter | 48V Split Phase | 21kW PV Input
The EG4 FlexBOSS21 is a split phase, all-in-one, hybrid inverter designed for the residential and small commercial markets. With a 21kW usable PV (DC) input, the FlexBOSS21 provides high power output, generating 12kW of AC power during non-sunlight conditions and a full 16kW AC with solar PV gain. It is a powerful and versatile inverter which can feed-through 90 Amps of utility power from the grid at 120/240 VAC.
The FlexBOSS21 is an enhanced cousin to EG4’s flagship 18kPV inverter that has been designed to optimally work with EG4’s GridBOSS MID (power gateway). The combination of FlexBOSS21 and GridBOSS significantly reduces installation expenses by replacing unnecessary components and reducing installation time. This makes the FlexBOSS21-GridBOSS combination an unbeatable choice for customers looking to build powerful, cost-effective and scalable solar systems.
Versatile and Powerful Hybrid Inverter
The EG4 FlexBOSS21 is a versatile 48V split-phase, hybrid inverter/charger that offers the same dependable power as the 18kPV with enhanced flexibility. Powerful enough to start a 5-ton AC unit, the FlexBOSS21 supports 21kW of PV input. Capable of paralleling up to 10 units together, the FlexBOSS21 has an impressive total output of 160kW continuous when using pv input. Three MPPTs give users optimal control over their solar needs, while the updated EG4 monitoring software allows for convenient total remote management, complete with mobile notifications and remote setting. Seamless interaction with GridBOSS gives users control over their entire Energy Storage System (ESS).

Free shipping applies to standard residential or business addresses only. This
covers 99% of our customers. However, if you live on top of a mountain, on an island with limited ferry access, need a plane or helicopter to reach your home, your nearest neighbour is a penguin, you live in a yurt in Death Valley that only donkeys can reach, or other remote location that delivery trucks cannot easily access or are outside of their traditional delivery routes, additional shipping costs may be incurred. We will contact you before shipping your order to confirm if additional charges may apply.

Larger items that would require shipping on a pallet would ship LTL.
Less-than-truckload, also known as less-than-load (LTL), is a shipping service for relatively small loads or quantities of freight. Less-than-truckload services are offered by many large, national parcel services as well as by specialized logistics providers.
Please see below for the shipping procedure for LTL shipments:
LTL Shipments may include appliances, solar panels, batteries, Cinderella Incinerating Toilets and wood stoves.
Curbside Freight Shipment Procedure-
Most appliances, solar equipment or larger shipment items ship via tractortrailer or straight truck and are limited to a curbside delivery. Freight carriers are specially trained and equipped to handle oversized and fragile items safely and efficiently. Please refer to the steps below to know what to expect for the delivery service. Please note that these items cannot ship to P.O. Box.
Step 1 – Within 24 - 48 hours after your order is shipped you will receive a confirmation email providing tracking information.
Step 2 – Once the shipment has arrived at your local freight terminal, transport will call you to schedule a delivery appointment. Appointments are made Mondays – Fridays and you are usually given a 4-hour window to expect delivery during business hours. It is important that the phone number provided when ordering is a working number to contact you. If an appointment is not made within a 24-hour period of being contacted, storage fees may apply. You would be responsible for these fees.
Step 3 – Curb side delivery completion – The driver will arrive with a lift-gate truck (truck sizes vary) and will lower the order onto the ground at the edge of your driveway. Due to company
policy the driver is not authorized to move it further. Curbside delivery service does not include set up or assembly of items, or removal of packaging materials, nor does it include bringing the items inside the home.
Step 4 - Upon delivery, you will need to inspect and sign a Proof of Delivery Receipt for the shipment. Check for visible damage and if any damage is seen make sure that it is noted on the delivery receipt and take pictures of the damage. You have the right to refuse the delivery due to damage shown. For all transport damage issues please contact us immediately. Please note: Shipping is unavailable to P.O. Boxes
What to know before accepting your delivery:
The Cabin Depot wants to make sure your order delivers on time, accurately, and damage free. So, we have some important information about receiving a new order.
We carefully inspect all orders before they leave our warehouse to ensure they are accurate and in perfect condition. If you haven’t received a shipping e-mail confirmation with tracking, and are curious about the status of your order, please let us know at any time by calling 1-844-603-4743 and select option #1.
Whenyour order arrives, you will need to carefully inspect immediately before the truck driver leaves or attempts to have you sign off on the paperwork. Paperwork is normally provided, and your signature requested by the driver to acknowledge your order was delivered. If they have no paperwork for you to sign (usually a BOL or Freight Bill) you can request it. Some drivers will want to drop your order and leave asap as they have other deliveries to make. But remember, you paid to have them deliver your order in perfect condition, and they will wait for you to inspect it. If you sign the delivery paperwork without noting any discrepancies or damage, the freight company will not accept a claim and make the customer liable for any damage discovered. So, this inspection means that you should: Open all boxes Count all items Ensure the items shipped are the correct model / type / colour.
DO NOT sign the driver’s paperwork unless you are 100% certain the order is complete, there are no missing items, and it has arrived in perfect condition.
IF YOUR ORDER ARRIVES INCORRECT OR IS MISSING ITEMS:
Note exactly what was shipped incorrectly or missing on your paperwork. You need to clearly write this on the BOL or Freight Bill. Take a picture of the products received, then contact us and we’ll investigate and get this corrected for you asap!
IF YOUR ORDER ARRIVES DAMAGED:
As upsetting as this may be, it does happen on occasion as careless drivers or warehouse workers may have mishandled your order. In this situation, you have 2 options: If there is
significant damage to the order, you can refuse it. Note “ORDER REFUSED DUE TO DAMAGE” on the paperwork, and make sure you take plenty of pictures of the damage. Then send this information to us so we can follow up with the freight company. We can then either refund your order or ship a completely new order to you if the product is still in stock and available. If there’s only slight damage to your order, you can still choose to receive it. But note this damage clearly on the paperwork and take several pictures. Then send this information to us and we will follow up with the freight company. They would then be liable to provide parts to repair or send you some form of compensation.
IF YOU INSPECTED YOUR ORDER, BUT LATER FIND DAMAGE:
This is known as ‘concealed damage’ and freight companies only allow 24 hours to file a concealed damage claim. So, it is very important that if you start unpacking your order and
discover damage to a part that wasn’t visible when you removed the packaging for initial inspection, you need to take pictures and contact us immediately. Do not wait. Freight companies will not even consider a concealed damage claim if one is filed more than 24 hours after receipt. Note that concealed damage claims are often denied, which is why your primary inspection as soon as the order arrives is so important.
