2.) Installation Overview
The RaVolt installation follows a standard process consisting of the following steps:
1.) Unloading Equipment-Trucks will arrive with a palleted enclosure, palleted generator,
concrete pads, and batteries. It is recommended to level and set pads first, and then set the
enclosure and generators directly off the truck.
2.) Placing the Enclosure & Generator Pads-Choosing a desired location for both pads,
typically on the northern side of the array, about 6 feet apart. This step also consists of
leveling and compacting the designated pad locations.
3.) Placing the Enclosure & Generator- Using slings and shackles on a capable machine
(skid steer, mini excavator, or tractor), rig and place the equipment on their dedicated
concrete pads.
4.) Trenching & Conduit- There will be 2 main trenches, the AC Out trench and the
generator circuit. The AC Out trench will be from the load center on the side of the unit, to
the AC disconnect on the side of the home. The generator circuit will be from the generator
to the enclosure.
5.) Terminations- The RaVolt unit arrives with pre-installed and pre-configured equipment.
There are roughly 10 additional terminations to make on a standard project.
6.) QA/QC, Commissioning, Photos- Installers will inspect the work using the QA/QC
guidelines. There is a short commissioning process to ensure process functionality,
followed by some photos for product warranties.
These 6 steps are broken down in greater detail throughout this installation guide.

Rev. 1.0 (12/19/2022) 7
3.) Unloading Equipment
Recommended Tools & Materials: Weight rated slings, weight rated shackles, ratchet
strap.
1. Determine a safe, flat location for the truck to park for unloading.
2. The truck will arrive with the RaVolt enclosure banded to a pallet, a palleted
concrete pad, and any additional batteries in crates.
3. Operator must ensure sufficient lifting capacity of the machine to be used.
Estimated equipment weights are below:
a. Estimated weight without batteries-600 lbs
b. Estimated weight with batteries-1100 lbs
c. Unit will usually arrive to site with batteries installed (1100 lbs)
4. If using a mini excavator for unloading the equipment, utilize properly weight rated
slings and properly weight rated shackles. The unit will arrive with 4 lifting points present
on the top of the enclosure. Operator must use extreme caution to not bend or break these
lifting points, which may interfere with the enclosure’s NEMA 3R rating. If using a forklift

Rev. 1.0 (12/19/2022) 8
or skid steer for unloading the equipment, utilize properly rated 4 foot forks for lifting the
pallets.
5.) If using a forklift or skid steer for unloading the equipment, utilize a ratchet strap to
secure the equipment to the mast of the machine when transporting.
6.) Place equipment in a flat, safe location until the crew is ready to progress.
4.) Placement of Enclosure Pad
RaVolt Enclosure Pad Dimensions: 4’ L x 3’ W
Recommended Tools & Materials: Shovel, rake, hand tamper, crushed gravel, 4 foot level.
1. Determine the best location for the placement of the RaVolt enclosure. Refer to the
project specific design documents when determining the general location. The
precise location should be flat and protected from erosion and other weather
factors.
2. Level and compact the determined location for the concrete pad. It is recommended
to utilize gravel or crushed stone for compaction to create a firm base. (See below
photos.)
3. Using a two-man lift, place the concrete pad on the level and compacted location.
Notes:
Pads can be placed in any homeowner-desired orientation. Units are usually installed on
the north side of the solar array for ground mount applications, or near the meter for
rooftop applications.
Installer must ensure the enclosure placement is outside of the minimum distance required
by code from an existing gas line or propane tank.
Installer must ensure placement allows for a 4-foot serviceable radius in front and on the
sides of the RaVolt enclosure. If there will be a generator present, ensure that there is 4 feet
between the enclosure and the generator.

Rev. 1.0 (12/19/2022) 9
5.) Placement of Enclosure
Recommended Tools & Materials: Slings, shackles, straps, snips
1. After the pad has been placed in its determined location, operator will begin to
properly rig and lift the enclosure for placement. It is recommended to transport the
unit on its pallet to the determined location, before removing bands for lifting and
placing.
2. Using all 4 lifting eyes on the RaVolt unit and appropriate rigging, lift the RaVolt
enclosure off the shipping pallet and place the enclosure on top of the placed or
poured pad.
3. Installers must ensure the unit is centered on the concrete pad.
4. Utilize the provided anchoring hardware to secure the unit to the pad.
5. Install the supplied drip edge after the enclosure has been set to ensure the NEMA
3R rating is upheld. The drip edge will fit in the three holes on the top of the
enclosure, on both the front and back of the unit.
6. These T30 bolts are already installed on the enclosure. Simply remove these bolts,
place the drip edge so the holes line up on the enclosure, and replace these bolts.

1.) After all terminations are made and the QA/QC walkthrough has been successfully
completed, the RaVolt system is ready to be turned on. Follow the steps in order to ensure
equipment is safe and functional.
2.) Make sure ALL breakers and disconnects are set to OFF prior to powering up any aspect
of the system.
PV Commissioning
3.) Make the MC4 home run connections on string one at the array to provide DC power to
the DC disconnect.
4.) Use a voltmeter to measure voltage on string one.
5.) Disconnect string one and repeat this process on all available pv strings coming to the
DC disconnect.
6.) Once all string voltages are verified and correct, replace the DC disconnect cover and
make all MC4 homerun connections at the array.
7.) Turn the DC disconnect dial from the “OFF” position to “ON”. This will send power to the
Sol-Ark inverter.
8.) Turn the PV disconnect switch on the Sol-Ark inverter from the “OFF” position to “ON”.
(Disconnect switch is “ON” in the horizontal, depressed position. “OFF” is the vertical
position.)
9.) The inverter should recognize the incoming DC voltage and light up the screen. Verify
the voltage reading on the inverter are the same voltages verified with the voltmeter. The
PV voltages can be seen by pressing the battery icon on the Sol-Ark.
Battery Commissioning
10.) Ensure all battery switches are in the “OFF” position. Also check to make sure all
communication cables are connected.
11.) Turn one battery on and verify the voltage using a voltmeter. Check to make sure the
Sol-Ark is reading a similar voltage.
12.) Turn the battery off and repeat this process with all batteries in the cabinet.

Rev. 1.0 (12/19/2022) 20
13.) Balance all batteries individually to within one tenth of a volt (.1 V) using the incoming
solar, making sure that the inverter is charging all batteries at an equal rate.
Disconnect Commissioning
14.) Turn off all batteries and the Sol-Ark. Remove the cover from the disconnect.
15.) With all disconnects, breakers, and equipment off, turn on the incoming power to the
disconnect. This may be a generator or the grid, test individually if both.
16.) With the disconnect set to “OFF” use a voltmeter to check the incoming voltage on the
line side of the disconnect. Check both phase to ground and phase to phase voltage to
ensure the incoming voltage is balanced.
17.) After voltages are verified from both the grid and gen inputs at the disconnect, turn the
power back off to the disconnect. Replace the cover to the disconnect.
18.) Turn the power on to the disconnect. After power is on, throw the disconnect switch to
allow power to the Sol-Ark.
19.) Flip the “Grid” and “Gen” disconnects on the Sol-Ark to “ON”. The Sol-Ark should
recognize the power and turn on.
20.) Verify voltage readings on the Sol-Ark screen coming from the grid and gen.
21.) With the battery disconnect off, turn the batteries on individually.
22.) Turn the battery disconnect on and verify that the grid and/or gen input is charging
the batteries.
IMPORTANT! Ensure that neutral and ground are bonded together at exactly ONE location
in the entire electrical system. This will be in the disconnect on the side of the RaVolt
enclosure.
Load Center Commissioning
23.) Remove the cover of the load center.
24.) Using a voltmeter, measure the voltage of the load side. Measure both phase to ground
and phase to phase voltages to verify that the voltages are balanced.
